My cat is vomiting and in pain after neuter. What can I do at home?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Longhair | Male | neutered | 10 months and 3 days old | 13 lbs

Loki was fine earlier, vomited 3 times within approx 30 minutes. First vomit contained a small amount of food, just liquid after. Did not smell like bile. Cries when picked up or even touched below shoulders. This behavior is completely abnormal. Was neutered on 22nd and given vax required. 10 months old, 13# Also dewormed. I'm post op with SI fusion, totally immobile. No car, no money. What can I do beyond observation right now? And thanks in advance.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Loki! I am sorry about your recent surgery! Causes of vomiting are: intestinal parasites, medications, ate something gross or plant material, foreign body (something is stuck), pancreatitis, hair ball, viral or bacterial infection, new food or treat, food allergy. For cats, there really isn't much to do at home. MOST (80%) of the time, with cats, the vomiting resolves. I would fast her-no food for 12 hours and with hold water for 6 hours. If she doesn't vomit in the 6 hours then put the water down. If no vomiting with in 12 hours then start feeding. I would line up help for Monday if she needs to be seen by your Vet. If she continues to vomit, won't eat and is lethargic the only thing we can do is have her examined. There are not at home medications safe for cats. I hope this helps and I wish you and Loki the very best!
