Hi my cat has been missing for a week and I have just got her out of a neighbours garage. She has obviously lost weight and she is also dehydrated is there anything that I can give her until I can get her checked out tomorrow. I have given her a small amount of food and unlimited water. I wasn't sure if I should let her have a large amount of food as I have heard it can cause problems if they haven't eaten for a long time. Any advice?
