Hello, everyone! I'm new to the forum and have a question for those of you who deal with stray cats on the regular. I had a female (i think) cat come up to my back door about a week ago and she has not left. I have a male indoor cat and I believe she was in heat due to the constant meowing and rubbing against the door. My question is how do I care for a stray and how do I know she doesn't belong to someone in the neighborhood? She doesn't look sickly or even that thin. Any advice is appreciated as I don't want to unintentionally "steal" someone's cat.
