My daughter and I rescued a little stray from the cold last week Friday. We took her to PetSmart for a quick blood test to make sure she didn't have any contagious kitty diseases. She had fleas really bad too. They gave her First Shield. This was on Friday. By Saturday afternoon all she wanted to do was sleep, and she was very lethargic. We didn't make the connection to the flea meds at first. Today (Monday) she is still lethargic, sleeps ALL the time. She does drink water, and is still eating, but she is very very warm to the touch. My daughter started looking up stuff about First Shield and found out all kinds of bad things. This has been happening all over the place. Lost of kitties and dogs have a bad reaction to it.....up to and including death. I am supposed to drop this kitty off tomorrow morning to a lady who has found a proper foster home for her. Now I'm scared to death. She is the most adorable little gray and white thing you ever saw. I'm trying not to worry too much since she is still drinking and eating, but she is just so lethargic. So sad to look at this beautiful little girl that doesn't even want to be held anymore............anyone else out there with the same thing happen to them? Any suggestions?
