The shows where I shoot require proof of vaccination. If I shoot any animal not in the show I ask the owner for assurances that shots are up to date and the animals are in good health. I interact with cats, and bites can occur, it is only good sense to be sure that Rabies and other shots are up to date.

I also sanitize equipment and backdrops constantly. Hard surfaces are treated with Oxyquat. When I come home my clothes go straight in the wash before my cats can 'check them out'. If I realize after a shoot that the animal was ill, I retire the backdrop and disinfect my whole shooting area. I don't allow toys or teases to be grabbed in the mouth, or if they do 'get it' the tease is retired. I also wash my hands or use hand sanitizer between each customer. In the rare case that I discover a cat is sick after the shoot has begun I have even thrown the ink pen away that the person used to sign up.

So, in short, I take it very seriously.
