Parvovirus can cause severe gastrointestinal illness and be fatal if untreated. It's not transmissible to people or cats, and officials say the best prevention is proper vaccination.

This all comes just days after an influx of 86 cats and dogs, with most coming from a dangerous hoarding situation.
