Check List for Spotting Possible Health Problems and Diseases

What you notice Possible causes you can eliminate yourself Cause of alarm if combined with these symptoms Possible diagnosis requiring immediate treatment by veterinarian
Droppings that are soft to runny and may smell sour. Anus and abdomen soiled with feces. Sudden change in diet (as from dry food to fresh), spoiled food, food or water that is too cold, intestinal problems caused by wet bedding or drafts.  Refused food, loses strength, sits in the cage trembling with fear, grinds teeth loudly in pain, bloated body, blood in stool. Poisoning from chemically treated produce; intestinal infection, most commonly coccidiosis (highly contagious to other rabbits and especially dangerous for young animals); be sure to take a long a stool sample; isolate the sick animal.
The rabbit stops eating and produces only tiny, hard droppings or nothing at all in spite of painful straining; body may be somewhat bloated. Too little exercise, insufficient water, abrupt change from fresh to all dry food; may be a symptom of an infectious disease or a result of eating spoiled food. Strongly bloated body, loud grind-of teeth, violent drumming with the back legs; shortness of breath and impaired circulation. Tympanites; take animal to the veterinarian immediately; may be fatal.
Some clear discharge from the nose, occasional sneezing. Irritation from vapors of strong cleansers or from dusty hay; vitamin deficiency; generally weakened resistance. (There are some rabbits that are allergic to hay!) Thick discharge of pus from the nose, which the rabbit tries to get rid of by snorting and wiping with the paws; chest and front legs sticky with mucus. Also, loss of appetite, general weakness, and coughing. Contagious cold (separate the animal immediately from other rabbits); beginnings of pneumonia, which often follows a cold.
Tearing eyes; reddened and, sometimes, swollen eyelids; discharge of pus from eyes. Symptoms of colds; irritation caused by dust or foreign body; injury from scratching bites, or overgrown wooly hair, (in Angoras, for instance.) Eyes swelling shut; lungs of dough- or jelly-like consistency on the head; more and more boils that erupt. Myxomatosis, which is practically always fatal; in areas where this disease is prevalent, rabbits should be vaccinated against it.
Accelerated breathing. trembling body. Overheating caused by direct exposure to the sun or proximity to hot radiator. Nostrils flaring; violently trembling body; mouth perhaps open; very fast, shallow breathing. Heat stroke; very serious; take the animal to the veterinarian instantly; if her or she cannot be reached, see instructions to emergency treatment!
Reddening of skin, minor loss of hair, small bald spots. Shedding in the spring and fall, allergy; vitamin deficiency; fur pulled out or bitten off by another rabbit. Considerable loss of hair, sticky and crusty scabs; frequent scratching; rabbit holds head at a tilt and shakes it. Mange (mite infestation), fungi.
Sitting around apathetically, moving too little. Loneliness; pining for a social partner; too little attention from humans; boredom; lack of interesting and stimulating place to run. (Rabbits also become more sedentary with age.) Rabbit no longer hopes or runs; teeth grinding indicating pain; legs sometimes pulled to close to body, sometimes stretched out unnaturally, sometimes dragged along behind; loss of equilibrium. Fracture; torn ligament; a joint pulled out of its socket; internal injury from being caught in a closing door or from being dropped; paralysis due to hereditary disease.
