My stray cat has a golf ball lump on his face and a fever. What is it?

I'm sorry to hear of your concerns with Bagheera. The most likely causes for an acute swelling such as that shown in the picture include an abscess, trauma or allergic reaction. I would recommend that you have him seen by your veterinarian. They may recommend a fine needle aspirate of the swelling to get a better idea of what's going on. If it is an abscess, surgery may be required to drain the infection.

It's likely that this lump is an abscess from a fight he had outside with another cat, you will need to take him to the vet in order to get it checked and treated, if it is an abscess it will need to be lanced and clean under sedation, he will also have an antibiotic injection to treat the infection.

This may be an abscess, a cyst or a tumor. You should have it examined by your veterinarian, as it is not possible to distinguish these by just looking at a photo. An abscess can usually be treated with antibiotics and/or be lanced, and a cyst can be evacuated. To identify a tumor, your vet may want to do a fine needle aspirate (he takes some material from the bump with a needle and then looks at it under the microscope) to determine whether the mass is concerning.

Hello, sorry to hear about Nathan. If he has a bump on his abdomen and has a fever, then she may need to be seen on emergency basis. That bump can indicate an abscess or a tumor both of which can cause a fever. Based on your cats age I think its more likely to be an abscess. Other causes of this include things such as FIP, FeLV or FIV as well as mouth infections. Nathan should be evaluated by his veterinarian to make sure he does not have any major infection or abscess that is causing this. Hope this helps and best of luck.

Hello. It is possible that Trico has a developing abscess, probably from getting into a fight with another cat. He may require antibiotics so it would be best to have him evaluated by your veterinarian as soon as possible. Hopefully, he will feel better soon. Thanks for using Petco Pet Education Center, formerly Petcoach.

A huge lump on his neck could be an abscess, a blicked salivary duct, inflamed or infected salivary gland, a cyst, a tumor, or a swollen lymph node. This needs to be examined by your veterinarian who will likely want to take a bit of tissue or check if and what kind of fluid is in the lump. He will do this with a very thin needle (painless) to determine what kind of mass or lump there is. Not eating is dangerous for a cat as this can cause liver disease in cats in addition to the original cause. Please take your kitty to a veterinarian for an exam today.

This could be a cat bite abscess. Your kitty may have been in a fight. If she lets you you can put a warm compress on it with warm epsom salt solution which may make the abscess burst. If it does not burst by tomorrow, take her to your veterinarian who can lance it. In case it is not an abscess your vet can then examine the lump or injury and treat it accordingly.
