Why is my cat acting weird with a chest lump and solid, bloated belly?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | spayed

My cat has just recently started acting weird. A few days ago she was limping on her paw, that has stopped but now I’ve noticed that she has a lump underneath her in the middle of her chest. Her abdomen also feels a bit bloated and solid.

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. 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!
