My Frederick is acting really strange. He slept alot today and when he got up he acted like he couldn't walk and would flinch when I tried to pet him. He would sometimes just fall over and isn't acting himself at all. Has anyone else had this happen? I took him to the emergency vet and they wanted to keep him overnight but I couldn't afford the $600 they wanted and they had no answer for me. I'm going to take him to the regular vet in the morning but was wondering if anyone had any ideas. Thanks!!
