Ear infections are common and painful problems for pets. In cats and dogs, ear infections typically are opportunistic and not contagious. They often occur when the ear’s immune system is disrupted by allergies, moisture, poor air circulation, or diseases such as feline AIDS. Under these conditions, bacteria and yeast that normally live harmlessly in the ear are able to proliferate to the point of infection.

Stomatitis is a markedly painful syndrome in which the gums and mouth become severely inflamed. The cat’s immune system plays a role in most cases of stomatitis. In these cases, the cat’s immune system begins to reject teeth in the mouth. In other cases, viruses such as FIV or FeLV trigger the syndrome.
Feline urinary obstruction is a life-threatening medical emergency. It occurs when a plug of mucus or a small stone lodges in the urethra and obstructs it. Strong spasms of the urethra may contribute to the syndrome. Because the urethra is the structure used to drain urine from the bladder, this situation makes urination very difficult or impossible.
An abscess is an area of infection and pus accumulation in the body. In cats, two types of abscess are common. Dental abscesses occur when unchecked periodontal disease leads to severe infection of the teeth.
