Hi Karen, yea she is spayed, but no no collar. My brother has bought her one many times but she always manages to get it off somehow and loses it, so he gave up trying to keep one on her. We've asked a few neighbors but no one has seen her. There are a lot of cats that wandar around our neighborhood so even if we tried to describe her to someone to see if they've seen her they probably wouldn't know for sure which cat we meant Thank-you for the prayers
