I just read on another thread about giving cats benedryl. I tried it once, gave the exact dose my vet said and it was awful. My poor Fred ran around in circles, screaming like he was on fire. Then when he got tired of running in circles, he flopped over on his back and kicked his feet and continued to scream. It was all I could do to get hold of him, put him in his carrier and get him to the vet. By the time we got there, he was ok, just very mad at me. I had heard of people using it with good results, so I felt ok giving it to him. Has anyone else had this happen? It was terrifying!
