Hi all, I'm new on this thread. I have a cat who has persistent, full body muscle spasms - you can see his muscles moving from across the room it's so bad. He licks and bites at the affected areas and runs around the house at full speed (trying to get away from it). At worst this can go on for most of the day with only short breaks for naps because he is so exhausted. My vet seems to think this is epilepsy related (we tried a steroid shot and that had no effect so he no longer thinks it is allergy related) but I really don't think this is epilepsy. My cat is always responsive and can sometimes even be briefly distracted by play. He can get a little grumpy when he has had a long episode but who can blame him really. He is only 3 years old and already on a hydrolyzed protein diet, so it's not a food allergy. If anyone has any idea what could be happening I would really appreciate some ideas, I hate seeing him his way and I don't want to put him on anticonvulsants for no reason. Thank you!
