Data were analyzed by analysis of covariance, adjusting for the following covariates: gender, source, sterilization status, and age. FCV — Feline calicivirus, FHV-1 — Feline herpes virus-1, B. bronchiseptica — Bordetella bronchiseptica, C. felis — Chlamydophila felis, M. feli — Mycoplasma felis. Inf — infinity.
