Blood blisters on a cat

Species: Cat
Breed: Moggy
Age: 11-15 years
My cat has developed what appear to be blood blisters, one just below her nose and another on her bottom lip. They become quite engorged until they burst, and then bleed profusely. Once the bleeding ceases they fill with blood again. They do not appear to cause the cat any extreme discomfort, but they worry me nonetheless. What could be causing these vesicles and what can be done?


Online vet, Dr. Marie

Dr. Marie replied:

This is an unusual situation.

I have seen cats get ulcers on their lips. These are usually something called eosinophilic ulcers (or rodent ulcers) and they are treated with steroid injections from your vet.

However, these don't burst open and bleed. In fact there is no common condition that can cause what you are describing.

There is a possibility that these are cancerous growths. It is also possible that she has a rare condition called pemphigus.

I would highly advise you see your vet about this condition. They should be able to tell you whether or not you should be worried and may be able to do something to help.

If you would like to reply I can give you an email address where you can send pictures to and I can see if I can help you out any more.

Dr. Marie.
