Soft lump on my cat’s shoulder which is growing? – question.3


On Friday a soft lump appeared on my cat’s left shoulder (just below her shoulder blade). I rang the vet on Saturday but they wouldn’t see her as they were busy.

Its grown pretty quickly and is now the size of half a golf ball. Its soft and regular in size. While it doesn’t bother her or hurt her, she has gone off her food (although she’s never been too bothered about her food, she is losing weight). She seems slightly restless, although she still seems fairly energetic.

Obviously I’ll get her to the vet as soon as possible, but has anyone experienced this before with an animal? I’m hoping as its soft it will just be an absess but you never can be sure.

Thank you

    just go to any vet as soon as possible even if you haven’t been there before. I’m sure it will be fine but its work checking (better safe than sorry)
    i hope it will turn out to be fine.
    Good Luck!

    Yes it could be abscess and that’s probably what it is. But it can always be something really serious. Be careful if you give her a bath not to get ANY soap on it. You never know what kind of effect it could have on it. Don’t touch it because the oils on your hands could make it worse. Definitely get to a vet ASAP. At least it isn’t hurting and that is a good sign. I hope all goes well.

    99% chance it’s an abscess. But there’s a remote chance it could be something serious. Vet visit is best.

    Abscesses are treated differently depending on if they’re young and not yet filled with pus, or if they’re mature and filled with pus. If it’s a young abscess, the vet will give antibiotics. If it’s ready to burst, they will shave and clean the area, then open it up to drain, and possibly give antibiotics too.

    Might be a fatty tumor, cancer or maybe a thorn or something got under the skin and fluid is collecting.

    it does sound like an abscess but i would get her to a vet asap, saying that with her losing weight that is cause for concern, i would like the comment said earlier to take her to any vet if yours cannot see her, it could also be fatty tissue or a cyst but it does sound like it has grown pretty quick. see a vet quickly to put your mind at ease and to get poor kitty sorted, hope she is ok.

    As previously mentioned, your description does harp of an abscess. These form most commonly from bite wounds inflicted by other cats, less commonly by wildlife and dogs. The canine teeth of cats leave deep punctures, which quickly seal over, trapping bacteria deeply under the skin.

    Cats can develop a fever due to abscess infection inducing an immune response, and fevers often make them anorexic. If the lump is near her shoulder joint itself, be concerned she could have a joint infection if she was bitten or punctured in the joint capsule.

    Other causes of lumps take longer to form a lump than 2-3 days, such as yours did. Vaccine associated fibrosarcoma, cancer related to vaccine administration, would still take weeks to form.

    DVMs who are observant clinically have noted that antibiotics are superfluous to treat abscesses, as the purulent material is walled away from the rest of the cat’s anatomy, and is not potentially systemic and risky to the whole body. Often, lancing the abscess, making a large opening that will not seal over, and flushing with dilute antibacterial solution, such as diluted iodine or chlorhexidine, is sufficient treatment, perhaps additional warm compressing and flushing over the course of 1-3 days while the wound heals from the inside out.

    Your hope that it is just an abscess is mine also. Warm compressing it now for 7 minutes may soften the puncture entry point enough that it opens and expresses the material within. But cat’s rarely go for that, as the pressure of the abscess is painful, and touching it is best done while the cat is sedated.
