Have Cat Questions? Ask a Cat Vet Online.
Hello. Thanks for writing in. My name is***** and I would be happy to help you. I am not set up to do phone calls but would be happy to answer any questions you do have online. If you get a request for a phone call, it is from the website and not myself. In order to give an informative and concise answer, it may take a few minutes before I respond back to you, so don't be alarmed if you don't hear back immediately if you have responded back to me within 10 minutes of my response. I do have a couple more questions, though, to see if I can better assess your situation.
How old is she?
Is she spayed? If so, how old was she when the procedure was done?
Does the mass seem painful or warmer to the touch?
Thanks for the information. My first thought is that this is most likely an abscess. It is possible that she punctured the areas one something, or it is a bite wound (most common cause of cat abscesses). It would definitely explain why she has been so grumpy. You can try putting a warm compress on the area for 5-10 minutes, but I doubt she would let you. The best course of action here would be to just have your vet check it out tomorrow. If they determine that it is indeed an abscess, then they will most likely need to drain it and start her on antibiotics. It is unlikely to be a mammary tumor with her young age and being spayed, so the only other thing that comes to mind is that she may have an inguinal hernia. That would usually be closer to the inner surface of the rear limb, though. Please let me know if you have any other questions or concerns. Hope this helps.
My goal is to make sure that you get all your question answered and all the information you need. If you are satisfied with my answer, PLEASE RATE IT. Rating it is the only way I get credit for helping you. If you feel like it is not helpful to you, or if there is more information you need, please respond back to me before rating. Realize that our conversation is not intended to diagnose or treat a condition. There has to be a valid veterinary-client-patient relationship established with an exam, according to law. You should always follow up with your vet.
Most of the time with an abscess, you won't see the sign of injury anymore because it has healed up. If she is older had gone through some heat cycles or even had kittens, then a mammary tumor is very possible, but it shouldn't be painful. A cyst in the mammary gland can develop as well and get infected, causing an abscess that way. A hernia would sit between the rear limbs. You may be able to reduce it back into the abdomen, but it shouldn't be freely movable. If a hernia is painful, though, that usually means something is caught in it. In that case, you probably wouldn't be able to move it much at all. The fact that it is painful is highly suggestive of an infection of some sort. Please let me know if you have further concerns.
Hello. I was just following up to see how your cat is doing and to see if you have any further questions.
Good. Hopefully that is all it is. Thanks for the update. Let me know if you have further concerns.
