Abstract
From April of 1998 to December of 2006, 262 cats with oral disease were treated in our hospital. Ninety-one of them suffered from chronic stomatitis without dental calculus or plaque. Among them, 75 cats were negative for both feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV), but from the lesions, feline calicivirus (FCV) was detected in 18 cats, accounting for 24 % of the FeLV negative, FIV negative, and calculus/plaque-free cats. Therefore the presence of FCV-induced chronic stomatitis was indicated.
