Feral or stray??? Please help!!
I have been feeding a little cat who showed up at my house one night in the early fall for about 2 months now. She is a shorthaired tabby. She will not let me pet her. Since I have been feeding her, she has definitely gained weight and often wants to sleep next to my front door. I have 2 (indoor) cats that like to also sleep at the front door, but on the inside. There is literally just the glass separating them. If I am in the house, I can go right up to the glass, only inches away from her and she is not afraid. But as soon as I go outside, she makes sure to be clear of me. I talk to her, she knows my voice.
I am so worried because I am in Michigan and it is getting really cold at night. I bought an insulated wood feral "outdoor house" but she will only go in it to retrieve food, and will not stay in it. How can I tell if she is just a really scared stray or feral? Wouldn't she let me pet her by now? I can tell she wants to be with my 2 cats. I am worried if I trap her and she is feral, (I would then have her neutered and re-release her) any trust she has in me will be gone. I am so worried about her. I often go to sleep feeling bad that we all have a warm house to sleep in and she is in the cold. Any suggestions are so greatly appreciated!!
