My kitten is vomiting and lethargic after neuter surgery. What's wrong?

Noodle might be sick. By this point, he should be completely recovered from the neuter. I recommend to ave him examined today if possible. He could have a fever, infection or a reaction to the anesthesia. Best to play it safe. I hope this helps and please feel free to post any additional questions.

I'm sorry to hear Zeko is so sick. These signs are not expected post-op and they are not normal. I would recommend to take him in to see a vet. Depending on how large your shelter is, they may have a doctor on staff to see these pets so call them but otherwise take him to see your regular doctor. Don't wait til after the holidays. Take him in either tonight or tomorrow asap. Best of luck with the little guy!

It is possible that he could have had a reaction to the anesthesia or just the stress of being neutered. Or it could be completely coincidental and it could be secondary to something else like parasites, foreign body, a sudden change in food, pancreatitis, an underlying infection, and much more. I would try to feed him some plain boiled boneless and skinless chicken and white rice. I would also try to start him on some probiotics. Your vet should be able to provide these or give you some recommendations. You can try some plain sugar free yogurt but the probiotics in this isn't as good as the cat probiotics because we have different bacteria in our gut than in cats. The next step should be to have him re-examined and likely have some bloodwork done. I would also make sure the vet has ruled out an parasites including giardia which is difficult to find on a regular fecal test. If your vet doesn't think there is a foreign body, they will be able to provide him with a good anti-nausea medicine to help with the vomiting. I hope this helps!

Thanks for using Petco Pet Education Center, formerly Petcoach! Yes, this warrants a veterinary evaluation. From what you describe, he is likely becoming dehydrated. They would be able to help with hydration and to treat the primary issue with supportive care. Good luck and have a great day! I wish him a quick recovery!

I'm sorry to hear that Roxas is not feeling well. Most neuter incisions, especially in young cats, heal very quickly and a week would be the minimum I would wait to give him a bath. I don't think you did anything wrong there. I would look at his neuter incisions and see how they look. Most of the time at this point they just have small scabs on them. As for the symptoms you are describing, I would recommend that he be seen by a veterinarian so it's good you have an appointment. It may be related to the neuter since it happened so recently, but it could be a completely separate illness. Please don't beat yourself up. You are doing the right thing in taking him in tomorrow.

I am sorry Miso is not feeling well. I would recommend taking Miso to the vet for a good exam, It is possible that Miso has gotten sick and it is not related to the neuter. Some cats can be sensitive to certain medications but can also get viral disease that can cause vomiting and anorexic. IT is best to have his temperature taken and a good exam to help determine why he is sick and proper treatment. I hope that helps

Is he still on the antibiotics? If so maybe you could call and request a different medication? If he is no longer taking the medication and he is still vomiting then she should have a follow up appointment. It is possible that it is just coincidental with the neutering and he could have a foreign body in his stomach, or a parasite causing him to vomit. They may want to do an x-ray and/or some blood work. Best of luck and I hope he improves soon.
