Mickey is the stray I adopted a couple of weeks ago who was eating everything in sight acting like he was starving to death. Over the last few days, he's been eating like a normal cat, which is good. This morning, he went to the vet and got his shots and was wormed. We just put a bowl of soft food in front of him and he took a couple of nibbles and went back to sleep. We went to a movie and were gone for a few hours and he was in the same spot and same position as before we left - I don't think he even moved. Should I be concerned or is it just the shots? He's going back to the vet Monday to get neutered, so should I just not worry until then?
