What is this golf ball sized lump on my cat's belly near his hind leg?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! There are many possibilities, Bubby may have an abscess from a bit especially if he is an outdoor cat, it could be a mat of hair if he is a long haired cat or it could be a tumor. I recommend having him looked at tomorrow by your Vet. Good luck!

It may just be a sebaceous cyst (a collection of oily debts under the skin) or a small area of inflammation from another cause. If its not painful and he isn't licking at it, I recommend that you make point once a week to measure it at home. If its changing in size over a couple of months or if it becomes bothersome, have it checked out at your vet. If your cat is too upset for a thorough exam, a little sedation may be recommended by your vet so that he/she can see what it is that you're seeing and make the appropriate recommendations. Thank for asking Petco Pet Education Center, formerly Petcoach!

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. This is likely from her mammary gland. There is no way of knowing for sure without an examination though this represents a reason to seek veterinary care. This is usually determined with an examination and a fine needle aspirate (FNA) or a biopsy. Treatment depends on the findings up to that point. I recommend you have Dahlia evaluated by a veterinarian for further assessment and treatment. Good luck and have a good night!

Hi, and thanks for your question. Although a picture of the lump would help to give you more specific answers, this growth should be ideally examined by your veterinarian to have a definitive diagnosis. Your vet will examine it and possibly perform with an FNA (fine needle aspiration) or a biopsy. Differentials would include skin cyst, infections or benign or malignant type of tumors.

There are several causes for a mass-like effect on a cat's side. there is the possibility of an infection/abscess from a wound. There could also be a tumor or a growth at the site. I would recommend Hallow be evaluated by her regular veterinarian to determine what it is and start on any treatment if warranted.

I'm sorry to hear that Al has a skin lump that you found. Cats can develop growths that are benign (cysts, fatty deposits) or some that are concerning (skin cancers, abscesses). I would recommend he be evaluated by his regular veterinarian to determine what kind of mass it is, and whether or not it is potentially a problem for him. Good luck!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Due to the location and the fact that Safari isn't spayed it is possibly a mammary mass. Due to her age it is most like most likely cystic or benign in nature that has developed due to hormonal influence. I do recommend a Vet exam for any new growths especially ones that involve the mammary tissue. I wish you the best!
