I just found a beautiful cat in my backyard. He comes up on my porch very willingly and comes up to me and meows. I leave him water and food and I'm sure he eats it. I don't think he'll be leaving anytime soon. But, I'm not sure if he has rabies or something. I haven't touched him yet because he has no collar. Should I be concerned that this cat has an illness, or is it okay to touch it? Also, what should I lave outside for him? Thanks a lot.
