I took in a stray cat back and June. Over time she has warmed up to us. Today she was spayed and she got home today around 4. She is indoor only and was sleeping the last time I saw her. She hasn't eaten since last night, so I figured she would be hungry by now. We have torn the apartment apart looking for her but cannot seem to find her. Any thoughts on if cats tend to hide really well after a surgical procedure? She was not a happy camper when she got home today. Any help at all with this situation would be very helpful.
