My cat is throwing up, skinny, aggressive, and in pain. What to do?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | unspayed | 2 years and 2 months old

My cat is throwing up, and is extremely skinny. She’s usually very sweet and social although she’s been hissing/growling and very antisocial. She’s been laying down in a weird way(for her) and when we try to get near she meows as if she wants or needs something but when we pet her she becomes very aggressive.

Poor Kitty! I am sure it is very distressing to see her uncomfortable. Persistent vomiting with weight loss is certainly very concerning and not normal. She is also a very young girl. She may also be in pain which is why she is acting the way she is towards you and laying differently. I would recommend she be seen by your family veterinarian as soon as possible so that they can examine her to try to determine was is going on. It is also likely that your vet may want to start with some blood work and/or take some xrays of her tummy. Can you think of anything that Kitty may have eaten that she shouldn't have? I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!
