Hamster Illness
Allergies
Hamsters can become allergic to bedding (particularly cedar shavings), some foods, cigarette smoke, perfumes, furniture polish, etc. It is also thought that some allergies are hereditary. Increased scratching, sneezing, runny eyes, swollen feet, wheezing or white flakes around the eyes and ears after the introduction of something new are a sign of a possible allergic reaction. Remove whatever has been added to the cage or food and watch for signs of improvement. If there is no improvement within a couple of days, it might be the result of an infection and veterinarian advice should be sought.
Bladder or Kidney Infection
One of the first signs is excessive drinking, which in turn creates increased urinating. Occasionally there is blood in the urine and the hamster may squeal in pain while urinating. Immediate veterinarian assistance is required.
Cancer or Tumors
Both internal and external cancerous tumors can develop. The external tumors are generally noticed as a hard lump that grows rapidly. It is possible for a veterinarian to successfully remove external tumors. However, internal tumors are not normally diagnosed early enough for surgical intervention. Symptoms include weight loss and a general appearance of being ill.
Cage Paralysis
A disorder resulting from hamsters being confined in a cage that is too small and doesn't allow it sufficient exercise. The symptoms include the hamster appearing to be semi-crippled by dragging its back end around. There is, however, a very simple cure and an even simpler preventative measure a larger cage and more exercise. It is also thought that diets low in Vitamins D and E may be a contributing factor to this condition. Vitamin supplements may be beneficial.
Cataracts
As in humans, cataracts normally appear in older hamsters and looks like a white film on the eye. Sometimes they are also a side effect of diabetics. Because this is an inherited condition, animals with cataracts should not be used for breeding stock. There is no treatment and sight loss is inevitable. However, since hamsters don't see well, at best, they can normally get around in their cage with no problems provided the location of items in the cage are not moved.
Constipation
Normally caused by an intestine blockage from commercial fluffy bedding or insufficient drinking water, especially in young ones. Other causes include lack of exercise, poor diet, pregnancy. On rare occasions, there is the possibility of Hymenolepis tapeworms in the small intestine. Symptoms are a swollen abdomen, which is frequently discolored and a bulging anus. Immediate treatment supervised by a veterinarian is essential to save the life of the hamster.
Diabeties
Although it can affect all species, diabetes is normally seen in the Campbells Dwarfs and is assumed to be an inherited disease. It generally strikes between 7 and 9 months of age and can be triggered by diet, stress or a dirty cage. Symptoms include excessive drinking and urinating and possibly shaking, trembling and a low body temperature. Severe cases can also result in a coma. Contact a veterinarian at the earliest signs. Although there is no cure for diabetes, steps can be taken to enhance the quality of life for the ailing hamster. For rehydration purposes, with veterinarian directions, a solution of unflavored pedialyte can be given in the water bottle. If a sugar free diet is recommended, the following can be fed: a good quality seed mix, alfalfa, carrots, potatoes and boiled egg. Don't feed any of the commercially prepared hamster treats since many of them contain molasses and corn syrup.
Diarrhea
Do not confuse diarrhea with wet tail Diarrhea is generally the result of overfeeding fresh vegetables and fruit, a sudden dietary change or mild stress. (Improperly cleaned water bottles with a build up of green algae can also cause diarrhea.) Symptoms include loose droppings that are lighter in color than normal and a wet or dirty "bottom." Remove all fresh fruits and vegetables and keep him/her on a diet of dry grains, burned toast and plenty of water. Fresh produce can be introduced after the condition has subsided for two or three days. If the diarrhea does not improve within a few days, veterinarian advice should be sought.
Ear Infection
Lack of balance and a tilted head are the normal symptoms of an ear infection. Antibiotics, as prescribed by the veterinarian will generally clear up the infection in a few days.
Ear Mites
Notoedres, the hamster ear mite, (a species specific) causes crusty lesions in hamsters' ears, on the face and feet. Treatment consists of either Ivermectin injections by the veterinarian or it can be administered orally.
Glaucoma
Seen in Campbells Dwarfs more frequently than the other species. It is thought to be inherited and hamsters with Glaucoma should not be used for breeding purposes. It appears as though the eye globe is swollen, which increases pressure on the eye. If the eye prolapses, removal can be considered.
Hair Loss
Hair loss in older hamsters is frequently seen as a result of chronic renal failure. Loss of hair can also be the result of rubbing on the wheel, leaking water bottle or abrasive bedding. A low protein diet is also associated with hair loss, generally a diet with less than 16% protein. Or a secondary dietary problem is overfeeding "heat" producing grains and cereals, such as corn. This is easily remedied by increasing fruits and vegetables in the diet or by feeding half the dry grain/seed mix with boiled rice or puffed rice cereal. There are two different treatments for general hair loss: 1) one or two drops of cod-liver oil daily; 2) crush a yeast tablet (without garlic, which is hard on hamsters kidneys) in top of the food for three or four days, then decrease to once a week.
Heat Stroke
Sometimes referred to as Sleeper disease. In extreme temperatures, hamsters are not able to cool themselves and can go into a state appearing to be a deep sleep. The rigid and lifeless hamster may tremble or move its head from side to side and the fur may be wet and matted. It can be splashed with cool water and should be placed in a cooler area and encouraged to drink after it has recovered. It is essential to rehydrate as soon as possible to avoid possible kidney failure. It should return to normal behavior in approximately 10 minutes. If not, veterinarian assistance should be obtained.
Hind Limb Paralysis
In a Syrian male around 6 months old, the onset of hind limb paralysis may be an indication of a hereditary defect. There is no cure and these animals should not be used for breeding purposes. Other possible causes could be from a fall, constipation or a cage that is too small. Veterinary advice is recommended in all cases.
Mange
A very contagious skin infection caused by mites. Symptoms include excessive scratching and dry flaky skin. Additional symptoms include hair loss and scabs around the genitals, nose and ears. Because it is so contagious, isolation is necessary to reduce exposure to other hamsters, humans and household pets. Extreme care should be exercised in sterilizing everything the hamster had contact with and washing hands with anti-bacterial soap after handling it. Immediate attention by the veterinarian is required.
Mites
When small "dots" are seen moving on the hamster and it is scratching excessively, the normal cause is mites, which can be caught from other hamsters or even bedding material. Isolate the infected hamster and dust both the hamster and the cage with pyrethrin powder or spray. A veterinarian should be consulted if the scratching persists or if there are indicates of Hair loss or a skin infection or scaliness.
Overgrown Nails
A common problem in older hamsters. They can be clipped with a pair of nail clippers provided extreme care is taken to avoid cutting the quick.
Overgrown Teeth
Hamsters are one of the few animals that are born with incisor teeth. Like all rodents, those teeth are continually growing throughout the life of the hamster. Normally gnawing on hard foods, a piece of wood, pine cones, etc wear down the teeth. The rate of growth can surpass normal wear if sufficient "gnawing materials" are not provided, or if there is a hormonal imbalance or, in a few instances, a congenital problem. When this occurs, it is essential to have the teeth clipped or the ever-growing teeth will block the mouth, which could result in death from starvation. A broken tooth, gum injuries or infection and some congenital problems can cause the opposite tooth to overgrow because there is no tooth to align with. If a tooth is broken or there are gum injuries or infection, the opposite tooth will become overgrown because it is not continually meeting with the other tooth to assist in the grinding process. Older hamsters, in particular, are prone to broken teeth. The teeth of hamsters with a calcium deficiency (the result of excess sunflower seeds) will also break easily. Since hamster's teeth grow so fast, they should be checked at least once a month and clipped if there is evidence of overgrowth. This is a relatively simple procedure; but it is recommended that the assistance of a veterinarian be sought for the first clip. Most vets will demonstrate how to clip the teeth so it can be done at home the next time around.
Sarcoptic Mange
This particular type of mange is quite rare; but very contagious. The mite Sarcoptes Scabei causes it. In humans, this disease is called scabies. The condition can be treated if immediate medical treatment is sought. Infected animals should be isolated and everything it came into contact with sterilized.
Shock
Occasionally a hamster can go into shock from a fall. Symptoms include shivering, lifeless and breathing heavily. Rub it gently to increase blood circulation and put it back in its cage, preferably in a darkened room. If signs of improvement are not seen within an hour, seek the advice of a veterinarian.
Stroke
Usually it is older hamsters that suffer from strokes; however, occasionally a younger one will be stricken. The first sign of an impending stroke is the hamster tires easily and may even collapse after using the wheel. Normally the hamster is paralyzed on one side, looses its sense of balance and sometimes tilts its head to one side. Keep the cage in a warm quiet environment. Until the hamster begins to recuperate, it may be necessary to hand feed and water it. It generally takes a couple of weeks before it is up and moving around. In some cases the head tilt is permanent. Even after recovery, it is recommended that the hamster be kept in an aquarium with no wheel.
Wet Tail
Also known as transmissible ileal hyperplasia. Wet Tail is undoubtedly the most common and one of the most serious diseases of hamsters. It is generally triggered by stress associated with weaning, environmental changes, malnutrition, dirty cages, and overcrowding. It used to be referred to as "shipping fever" because inadequate and overcrowded shipping boxes and being exposed to several different environments is extremely stressful to young hamsters. Especially since they have just suffered the trauma of being taken away from their mothers. Fortunately there are now products available that will balance the stomach's pH and also help reduce stress. Wet Tail is, in fact, a severe case of watery diarrhea that can result in death from dehydration within two days if left untreated. The hamster is lethargic and usually sits in a hunched position. Very extreme cases can cause a rectal prolapse or intussception. It is imperative that a veterinarian be contacted at the first signs of wet tail. Unless immediate emergency measures are taken, treatment may be unsuccessful. It is essential to keep the hamster in a warm clean cage with adequate ventilation, but not a draft. Since dehydration is the primary cause of death, it is imperative to give warm fluids immediately. As an emergency rehydration fluid, until the veterinarian recommends something else, they can be given unflavored pedialyte (available in most grocery stores). All food should be removed the first 24 hours. Antibiotics, as prescribed by the veterinarian, may include neomycin or metronidazole. Injections of multivitamins, especially Vitamin B, can be helpful. Vitamin B can also be given in the form of nutritional yeast. Prevention, in this case, is obviously more effective than treatment. All measures should be taken to reduce stress; clean cages and bedding are essential and a good balanced diet. Dwarfs very seldom get wet tail; but it is quite prevalent with Syrians. At the first signs, isolate the ill hamster from all other hamsters because severe cases can be contagious. Sterilize everything the hamster has come into contact with and thoroughly wash hands with an anti-bacterial soap both before and after handling the hamster or anything that has been exposed. The bedding should be changed daily and the soiled bedding disposed of. In the event of death, dispose of everything the hamster has had contact with that cannot be thoroughly sterilized. Diluted household bleach works well to sterilize the cage, food dishes, water bottle, wheel, toys, etc.
COMMON INJURIES:
Abscesses
Usually the result of cuts and bites that have either been overlooked or haven't been properly cleaned. Once an abscess (a lump filled with fluid) has developed, a trip to the vet is required. The verterinarian will likely lance the abscess and then drain it. After the procedure the veterinarian will probably prescribe antibiotics for a time while the wound heals.
Broken Limbs
Normally the result of a fall. If a broken limb is suspected it is best to obtain the advice of a veterinarian who probably will NOT wrap or splint the break since it will only be a matter of time before it is chewed off by the hamster. The limb may not heal straight but this won't likely affect the resilient little hamster. However, if the limb is being dragged around or it looks to be inflamed, vet assistance should once again be sought. To allow healing time without additional injury, the hamster should be moved to an aquarium (no barred cage as the hamster might try and climb), the wheel should be removed and any other toys that would require the use of the broken limb. Keep the little one as quiet as possible and let the broken limb heal naturally.
Cuts and Bites
Young pups sometimes get a little overzealous in their squabbles, and sometimes fights may break out as the result of an unsuccessful mating attempt thus potentially causing cuts and bites. The injured hamster with just minor cuts and bites should be placed in a separate cage. They will then lick and clean the cuts and bites, which should heal quite quickly. More serious cuts and bites should be tended to by cutting the hair from around the would with blunt scissors. To prevent the cut hair from falling into the wound, wet the scissors and the hair will cling to the scissor blades. Once the hair has been removed, was the area with a saline solution or peroxide and coat with a good antibiotic ointment. Veterinary treatment should be obtained at the first signs of infection or the start of an abscess.
Impacted Cheek Pouches
Hamsters' cheek pouches are dry, not moist like a human's, and they can become impacted if he/she is unable to extract what is in the pouch. Sticky foods, commercial fluffy bedding and some sharp pointed seeds are the most common culprits. An impacted pouch will appear as a lump (sometimes resembling an abscess) and on occasion can be so large that it causes the eyes to close. There is no effective home remedy for this condition, the pouch needs to be emptied and rinsed by a veterinarian. This is one of those situations where an ounce of prevention is worth a pound of cure, don't feed sticky foods that could adhere to the inner lining of the pouch and be aware of anything given to the hamster that it might store in it's pouch. Like small babies that tend to put everything in their mouths, a hamster tries to put everything in its pouch!
Irritated Eyes
Occasionally an eye can get scratched during a squabble with another hamster. Or it can become irritated from something in it like dust, dirt, a wood chipe, etc. If the eye is "matted" shut, soak it with a wet washcloth, warm (not hot) water please! This may have to be repeated several times before the eye opens. Once the eye is open cleanse with saline solution (the saline solution made for contact lenses is sterilized and works well). Boric acid can also be used. Normally eyes heal very rapidly. A veterinarian should be consulted in the event of a serious eye injury or if the redness persists. The saline can be used straight from the bottle. However a solution needs to be prepared if you use Boric Acid (mix one teaspoon of Boric Acid with one-half cup of cooled boiled water.
