Debbie - as you know I'm new to cats but I did get Meka from the local Animal Control. She took a little time to settle into the "new" house and get her nerves settled. Also she still getts diareah when I change her food to soft food for some reason. So I give her the hard food. I even bought the same brand of soft food as the dry food and it just seems to go right threw her. I can give her my food and she is fine or hard food BUT NOT soft food.. I'm just saying it is probably nerves... Glad you are taking the new kitty in and please keep us updated on what they say. BUT dont' worry... He is so lucky to have you! Debbie
