I would be concerned about this lump in your cat. It could just be some fatty tissue in her mammary glands, which is very common to have, if it is the same on both sides. It's however the lump is only on one side of her tummy then that increases my suspicion that it is a tumor of some sort. I would recommend having a fine needle aspirate and cytology done at your vet. This is when a small sample of cells is taken from the mass and looked at under the microscope. This can help your vet determine if the mass is something benign or malignant (cancerous). If it is a malignant mass it needs to be removed sooner rather than later because it is already fairly large.

    Hi, and thanks for your question. Although a picture of it would help to give you more specific answers, this lump/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. 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!
