These rabbits will need to have their teeth trimmed frequently or have them extracted. Because rabbits groom themselves frequently, they are susceptible to intestinal hairballs. Signs of hairballs include sudden lethargy, and a decrease in droppings. If a hairball is suspected, treatment should be started by a veterinarian right away. Remember that pet rabbits that refuse to eat need veterinary attention immediately.
Ear mites can burrow in rabbit's ears and cause crusty, painful ears.
Your veterinarian can test for these, and give an injection to kill the mites in rabbits that have them. Your rabbit is also susceptible to fleas, lice and a fungus called ringworm. Minor skin lesions may indicate your rabbit has one of these problems, so call your veterinarian if you notice skin sores or hair loss. Watch for warning signs of sickness, such as slobbering anorexia diarrhea teeth grinding decreased droppings nose or eye drainage lumps and bumps wobbling weakness or refusal to move. Rabbits are prey animals and often mask signs of disease.
