Adverse events after vaccine administration in cats: 2,560 cases (2002-2005).

Objective: To determine the incidence of vaccine-associated adverse events (VAAEs) diagnosed within 30 days of vaccination in cats and characterize risk factors for their occurrence.

Design: Retrospective cohort study.

Animals: 496,189 cats vaccinated at 329 hospitals.

Prevalence and risk factors for Giardia and coccidia species of pet cats in 2003-2004.

Prevalence and risk factors for feline coccidia and Giardia species infections were estimated for cats visiting 434 Banfield hospitals in 40 states in 2003-2004. Evaluated were 631,021 cats making 1,456,712 office visits (encounters) and having 211,105 fecal examinations. The overall fecal prevalences of coccidia and Giardia species were 1.
