Sick Bunny: Is Your Rabbit Ill?
The following are common health issues that may indicate your rabbit is sick and could need treatment.
Red rabbit urine
A rabbit’s urine can vary in color from clear to yellow to brown to bright red. None of these colors are a cause for alarm unless there are additional symptoms — such as sitting and straining to urinate, loss of appetite or an elevated temperature. When you see red urine, don't panic; it doesn’t necessarily indicate blood in the urine. But do keep your eyes open for other signs that may indicate a problem. The red color will usually be gone in a day or two, but it can last much longer. Actual blood in the urine looks like urine with red specks. If you're in doubt, don't risk your bunny's health: Have your veterinarian test for blood in the urine.
Hairballs and intestinal blockage in bunnies
Rabbits shed their hair every three months, alternating between heavy and light periods. Because rabbits are very clean and are constantly grooming themselves and/or their companions, they ingest a great deal of hair. Over time, this hair may build up and block the stomach exit, causing the rabbit to starve to death while his stomach appears fat. Unlike cats, rabbits cannot throw up a hairball when it threatens their health. Needless to say, hairballs are a major cause of problems, and even death, in rabbits.
The first sign of a hairball or intestinal blockage of any kind is a loss of appetite. The rabbit’s droppings will get smaller and will often be strung together like a string of pearls or will contain hairs or pieces of whatever the bunny has ingested. The rabbit's stomach will then become bloated and he’ll lose weight. The bunny may also appear to be in pain. Seek immediate medical attention if you suspect a hairball problem.
To prevent blockages, regular brushing and combing of your rabbit is vital. Also, feed your bunny unlimited timothy hay every day. Don’t use the small compressed hay blocks because the fiber is too small and is therefore ineffective. Make sure your bunny gets plenty of exercise (so the hair she ingests can pass through her system), and occasionally offer her fresh or frozen (not canned) pineapple, which contains bromelain, an enzyme that helps break down the hair. Laxatives are probably not a good idea, since they tend to dehydrate rabbits. Consult your veterinarian if you are considering use of laxatives.
Teeth: Malocclusion in rabbits
Rabbit teeth are constantly growing, which is why they are always chewing — to help keep their teeth the proper size. Some rabbits, however, have misaligned (maloccluded) teeth, which do not wear down properly and continue to grow. A rabbit with this condition needs to have his teeth clipped periodically so that he can eat. Your vet can do this for you or can show you how to do it yourself.
Very rarely, when there’s extreme malocclusion, a bunny will need to have his front teeth removed. These rabbits do just fine as long as you cut their food into small pieces. You can easily see misalignment of the front teeth, but your bunny’s back teeth may need to be checked by your vet. One indication that the back teeth may be a problem is wetness on your bunny’s chin, caused by drooling. Check your rabbit’s teeth during each grooming session.
Rabbit sneezing, runny nose and runny eyes
Sneezing may or may not be a sign of trouble. If sneezing is accompanied by a runny nose and/or runny eyes, you should take your rabbit to the veterinarian immediately, especially if there is also a loss of appetite. If the rabbit is sneezing but has no other symptoms and is eating well, the cause may be allergies or even nothing at all, but keep a close eye out for the development of any other symptoms and keep in touch with your rabbit vet.
Bunny parasites: Fleas, mites and internal parasites
Like other pets, rabbits can get fleas. Because rabbits are very sensitive to chemicals, be careful about the products you use on your rabbit, as well as the products you use to treat your home and yard. If the use of chemicals is absolutely necessary, look for products that are safe for kittens. If you treat your yard, do not allow your rabbit in it for at least a week, and only after you’ve watered the yard thoroughly to wash off any residual chemicals.
Here are other common parasites that your rabbit might get:
- Skin mites live on the skin dander of rabbits and will cause your rabbit to scratch. If left untreated, they will eventually cause thick crusts to develop on the rabbit's body. Your vet can administer a drug called Ivermectin to treat this problem.
- Ear mites cause rabbits to shake their heads frequently and scratch their ears. If left untreated, a middle-ear infection could develop, which may cause a problem with the bunny’s balance. Ivermectin is also recommended for ear mites.
- Internal parasites called coccidia can infect the small intestine. Symptoms can range from a loss of appetite to chronic diarrhea and, occasionally, death. Testing for coccidia is as easy as taking a fecal sample to your vet.
- Many pregnant women and their doctors incorrectly believe that rabbit feces carry disease that may result in toxoplasmosis from cleaning a rabbit’s litter box. Rabbits cannot carry or reproduce the spores that are harmful. Unfortunately, many rabbits are abandoned because of an unfounded fear of toxoplasmosis.
If your rabbits are free of any of these parasites, it is unlikely that they will get them as long as they are kept inside, their home is kept clean, and they are not exposed to other animals that may carry these parasites.
Amoxicillin: Dangerous for rabbits
Amoxicillin is very toxic to rabbits, so don’t ever let a veterinarian give your rabbit this antibiotic, which is pink in color and smells like bubble gum. Amoxicillin and other forms of penicillin kill the beneficial bacteria in the rabbit's intestines and can cause other organs to malfunction.
There are other antibiotics that can safely be given to rabbits, such as Chloromycetin, Tetracycline and Baytril. Occasionally, a rabbit cannot tolerate an antibiotic (some signs are a loss of appetite and diarrhea) and another may have to be tried instead.
Rabbit medical emergencies
Ask your rabbit vet about the proper procedure in the event of an emergency that occurs after office hours or on a holiday. Some veterinarians will refer you to an “on-call” vet and others will send you to an emergency clinic. Keep in mind that many clinics do not have exotic pet vets on staff. They will stabilize your rabbit, but you will have to follow up with your rabbit vet the next day.
Conditions that require emergency care (within 24 hours) include these:
- Diarrhea with listlessness
- Loss of appetite with bloat and/or abdominal gurgling
- Loss of appetite with labored breathing
- Loss of appetite with runny nose or eyes
- Head tilt or loss of coordination
- Abscesses and/or swelling
- Any sudden behavior change
- A thick nose or eye discharge
- Any sign of severe pain (loud teeth-grinding, hunched posture, shallow or rapid breathing, excessive grooming, reduced activity or facing the corner with head down)
