He may not feel like eating just yet as it is common it can take a day for his appetite to come back. I would let him rest today and let the medication start working. Try his food or even a little tuna in the morning. If he is still uninterested then you might want to get him rechecked for further testing

Often times the appetite does not return until 24 hours after the injection. Since he is drinking and not vomiting that is a good sign and he is not getting dehydrated. It is common for them to feel a little lethargic also. Try some food every 8-12 hours to test his appetite, if no appetite returning then get him rechecked

Without knowing the type of injection, it is difficult for me to say if one has anything to do with another. If it was a simple vaccination, this can be a pretty typical side effect from something like this. I wouldn't worry as long as the refusal to eat doesn't last greater than 24 hours. If you want, you can try offering something like hamburger, tuna, or chicken just to whet his appetite. Just don't give too much as you may cause some diarrhea in such a young kitty. Hope this helps!

My cat won't eat or drink after vet visit for vomiting. What to do?

If he was recently at the vet for vomiting, and now is not eating or drinking anything, he should be seen again as this would make me concerned about the possibility of a foreign body, or pancreatitis, which would require additional therapy. If your vet didn't do x-rays or bloodwork at the previous appointment it's time to make sure there's nothing more serious going on. However, since your vet just saw Iron I would start by giving them a call with an update, in case they have other input based on their exam findings. Hope this helps and he feels better soon!

Why is my cat sleeping and not eating after an anti-nausea shot?

Lethargy can be a side effect of an anti-nausea injection such as Cerenia, so that could be why Sunshine is just sleeping. I would monitor her for now, and see if she will eat when she wakes up. You can try to tempt her to eat by offering her some boiled white meat chicken (no bones). If she is still refusing to eat in the morning, I would bring her back into the vet.

My cat is lethargic and not eating after vet shots. Is this normal?

No, this isn't normal behavior. While you can see a decrease in appetite and some lethargy, it's an unusual reaction to have a cat refusing to eat and drink, as well as not want to move. I would try to tempt her to eat by offering her some boiled white meat chicken (no bones) or soaking her food in tuna juice. If she still refuses to eat, then I would have her seen by a vet.

My cat won't eat after vaccine. Is this normal or should I worry?

Some poor appetite can be considered normal after vaccinations. Vaccines stimulate the immune system to help protect your pet from common diseases they could be exposed to. Vaccines can sometimes cause minor changes in appetite or behavior. Usually I tell clients some decrease in appetite and decreased activity can be normal for 24 hours but for any issues lasting more than 24 hours they should call me ASAP. Some of the major issues (although rare) associated with vaccine reactions are trouble breathing and anaphylactic shock. If you notice any trouble breathing, severe lethargy or swelling of the face or at the vaccine site you should contact your veterinarian as soon as possible. If the poor appetite is still an issue after 24 hours or If any other issues are going on contact your veterinarian ASAP.

My cat has URI, no improvement after shot. Why won't he eat or drink?

Poor Sourpatch! You typically should start to see some improvement within 24-48 hours, but it can be longer based on the severity of the infection. He likely isn't using the litter box because he hasn't eaten or drank, so he has no need to pass anything. When cats have a respiratory infection, they can't smell their food. Smell is very important to cats, and they won't eat something if they can't smell it. To tempt him to eat, I would gently warm up really smelly wet food, such as sardine or fished based. That will get some moisture in him as well, and hopefully he will start eating soon. If he still isn't eating after trying this in another 24 hours, I would take him back into the vet.

My kitten is sick and won't eat after vet visit. What should I do?

What a cute kitten! Offering a meat flavored baby food may help entice him to eat. Warming his food may also allow him to smell it better which will help his appetite. Offer him small meals several times a day as his stomach is too small to eat a lot at one time at this age. Definitely have him rechecked by your veterinarian if he's not eating by tomorrow. I hope he's feeling better soon.

My cat vomited, is lazy, and won't eat. Should I be worried?

If Jack hasn't had tune in water before, then this new food could have upset his stomach. His stomach may still be queasy from vomiting the day before, and he simply may not want to eat a lot due to that. It's good that he ate a little, and I would not worry just yet. Should he not want to eat at all tomorrow, then I would take him into the vet for a health check.
