I have a small female rescue, about one and a half years old. She was malnourished at first but fully recovered, although she has periods of diarrhea (not lately, AFAIK). Yesterday I petted her and noticed what felt like curly ropes in her abdomen, from upper chest to groin. I gave her parasite medicine and called her vet, who had no idea. The cat is fine and happy, eats, purrs and plays, but the "ropes" are still there. They seem attached to the skin, somewhat. I suspected her intestines might have slipped somehow, but I can not feel anything "missing" in that part of her. If nothing changes she goes to the vet, but the vet suggested to wait a few days and see. I just worry. Any idea what it could be?
Edit: On a phone consult, the vet suspected swollen ovaries due to the cat having been in her first heat recently. Not confirmed, but seems very plausible. Other suggestions are still accepted.
