Hi guys, I have tried searching the forum for the answer but cannot find exactly what I'm looking for. There is so much info on the communicable cat diseases, but what I want to know is exactly *how* contagious they are? A tiny, skinny, adult feral showed up at my house a couple weeks ago. In that short time, he's gone from exiting the yard at first sight of me, to eating from a dish when I leave, to eating from the dish in my presence. Just yesterday he came and rolled over on my foot briefly, almost as if to say thanks, before taking off. Today he has started crying at my back door for me. I am so terrified of inadvertently tracking in some sickness or virus to my indoor cat. I recognize that these cat illnesses are often transmitted through saliva - but are there any that are more contagious than that? Like, can I carry anything in on my clothing or feet if the feral touches me? (Disclaimer: I've never been a cat person til a couple years ago when I took in my first stray cat, so my knowledge is still limited, forgive my ignorance.) I take my shoes off at the door when I re-enter the house, run and jump in the shower, toss my clothes in the washing machine, and sanitize my shoes. I know this might be overkill but until I know the answer, I can't risk bringing anything in to my cat. This feral is an un-neutered male and has some battle scars. Thanks for your insight!
