Why is my cat suddenly attacking his tail, eyes dilated, growling?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered | 1 year and 3 months old | 10 lbs

My cat started attacking his tail about a month ago. He could be acting normal and all of a sudden his eyes get dilated and he just growls and goes after his tail. I’m so concerned. I took him to the vet but they told me to give it some time. I don’t want him suffering anymore. I don’t know what to do.

Hi, thanks for using PetCoach! Can you talk him out of attacking his tail or is he "out of it"? If he is out of it I would worry he is having a seizure and I would recommend video taping it and showing your Vet. If you yelling or trying to play with him makes him stop then it may not be a seizure, it might be boredom. I would start playing with him more and providing environmental enrichment to his life. If he is older then I would get some blood work done and have his blood pressure checked. I am assuming your Vet checked him for pain and fleas. I wish you the best! https://indoorpet.osu.edu/sites/indoorpet/files/assets/documents/Herron10_EE_for_Indoor_Cats.pdf
