I have been adopted by a very affectionate gray tabby. She had been coming around more and more to the point that I decide to feed her. I noticed that other neighborhood cats were coming around and eating her food so I started feeding her in my laundry room. Once she got comfortable with this arrangement I invited her into my home. She has taken to being inside rather well. She gets curious about certain areas but doesn't cause any damage or get into anything dangerous.
I took her to the local Humane Society for rabies, vaccines, etc. She had been spayed and does not have a microchip. So she is now my cat. When I am home, she stays inside with me and behaves very well. When I go out for anything, i.e. school, errands, etc., or when I go to bed, I will put her outside and she will be waiting for me when I get home or the next morning.
At what point is it safe to leave her in the house during the night and when I am away from home? I did read a post (Cat in a electronics hobbyist house) about how to keep the environment safe for her, but I am not sure how I can tell when "all is safe" for her.
