My cat has weird itching spasms despite being flea-free. Help!

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered | 3 years and 4 months old | 15 lbs

Hello, my name is Heather I am currently having an issue with my cat. I believe it is a skin related issue because this all started after my cat got fleas. We went to the vet and got treatment and he has been flea free for the past five months but he is still having these very weird itching spasms. I have a video of what it exactly looks like but I have tried everything to try and help kahlua. Ranging from moisturizing shampoos to fish oil to coconut oil to asking a vet and nothing works.

What a handsome boy! There's a few things you may try. To absolutely make sure fleas are not the cause (remember, if you have a pet who is sensitive, tit only takes 1 flea to cause a reaction), talk with your veterinarian about using an oral flea prevention called Comfortis. Try this for 2-3 months and see if it helps. Kahlua looks a little heavy, sometimes this can prevent them from being able to clean the lower back/around the tail. Weight loss will allow him to adequately clean that area and in the mean time, shampooing the area every 4-5 days or using a dry shampoo and a brush every 3-4 days will help to decrease the oil production and decrease itchiness. Continue using a fish oil though I prefer an omega 3 fatty acids supplement. Changing the food to Royal Canin may also help improve the skin quality. Allergies can also cause itchiness but I recommend to rule out the fleas first. I hope this helps.
