I have just started keeping Seramas as house chickens. For many years I was involved in breeding and showing pedigreed cats and my family fosters dog rescues. Unfortunately we have had "fun" with ringworm, tapeworms, and staph skin infections that are all zoonotic (shared between species including from pets to people). My post is not to discourage having housepets, but to encourage good hygiene. Isolate and bathe new critters (Nizoral is antifungal for ringworm, Hibitane is antibacterial for staph), wash soft surfaces like clothing and carpets (Virkon kills ringworm and many diseases without bleaching) and put into a hot drier or a deep freeze, use bleach and water routinely as a safe household disinfectant (1:10). Those of us who show, rescue, visit places with animals, or who bring new critters home are most at risk.If your animals are healthy and you aren't bringing new ones in or visiting risky places then simple soap and water does the trick most of the time.I have never had any disease transfer from any of my critters, unless you count couch potato disease.
