My cat has spreading blisters on her belly, is it from new litter?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | spayed | 10 years and 5 months old | 14 lbs

I noticed what looks like blisters on my cats belly.. started with 2 and now its spreading fast. Only thing I've done differently was litter. Her name is Zen and she is 10 years young. I'm taking her to the local vet tomorrow but I'm losing sleep over this. I'm very worried. I don't believe she is in pain. She lets me hold her and her appetite hasn't changed.

Hi, and thanks for your question. This could be due to an allergy, although it could also be infection or mites. First of all, in order to rule out skin parasites, you will need to treat with a high quality flea treatment, then ask the vet to perform a skin scrape - this might reveal an infection or a mite infestation. If all of those came back negative, the next step is to treat the allergy symptomatically and try to discover the cause of the allergy. Three main type of allergies are usually affecting pets: food allergies, flea and parasite related ones and environmental type (allergens coming from trees, pollens, dust etc etc). Some medications can be given by the vet in order to repair any possible skin lesions (like steroids and antibiotics). Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further. If this answer was helpful please let us know, this will be used to improve our service!
