I had lost a cat earlier this year, approximately 3 months ago and had found him again. He seems to have recognized us but he seems to want to go outside. He has had no vaccines or any checkups so I know that's a problem. We are going to let him go once more and hopefully he'll come back.
My cat Shadow vomited 2 times today and I too worry about my feline friend. We have changed the food. I have no idea how old he is but he's pretty old.
