My cat is sleeping a lot and sore after vaccine. Is this normal?

This sounds like a side effect of the vaccine, it's not super common but i'v seen a few cases already and this usually resolves within 48-72 hours. your vet could give her pain killers for a couple days if her condition seems to be really bad.

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.

It can be normal for kittens to be somewhat tired and sore after vaccination, just like human children. Some may run a low-grade fever and not eat well for the first day or so after their shots. What is NOT normal would be any of the following symptoms: repeated vomiting, pale gums, difficulty breathing, or collapse/extreme weakness - these are signs of a serious allergic reaction. This is very rare following vaccination, but if it occurs it can be life-threatening - so if you observe any of these signs, make sure to get your kitten to the vet right away. If she is just tired and sore, it should be fine to monitor her at home - she should be feeling better within the next 24-48 hours.

This can be normal. Getting vaccines can cause a cat to feel off for a couple of days. I'd just keep an eye on Baby for now. If you see a lot of vomiting, diarrhea, severe lethargy, facial swelling, hives, or difficulty breathing, that is not normal and she will need to see a vet immediately. Otherwise, this should pass shortly. I hope this helps!

Poor Casper. Some cats can develop fever or soreness after vaccination. If he is very sore, not eating and sleeping excessively it's worth considering a visit to the emergency vet for Casper to be evaluated and medicated to treat a possible vaccine reaction. If he is sleeping more but still getting up to eat and drink and use the litter box it may be a milder reaction that will subside with time. in either case be sure to let his regular vet know so that he can possibly be pre-treated with medication before vaccines from now on. Hope he feels better soon. Do Not Give any OTC pain or fever meds to Casper. Cats cannot metabolize many human medications and they can be fatal.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. If the vaccinations were given recently, the decrease in activity is sometimes seen secondary to the vaccinations. If this continues or worsens that I would recommend having a veterinarian take a look at Kiara so that The most appropriate Diagnostic and treatment recommendations can be made. I hope this helps guide you in the right direction. Please let me know if you have any further questions or concerns and I would be more than happy to help you further.

I'm sorry that Tilly is acting this way. I suspect she is having some "normal" reaction to the vaccine, in that she is a bit sore and tired, and stressed from yesterday's ordeal. Give her some space and time. Make sure she has food and water closeby and a box or another comfy place she can "hide." She will probably come around to her old self in the next couple of days. If her appetite continues to be poor or if she isn't more energetic within 24-36 hours, though, please call your vet to discuss. It may be warranted to get her back in for an exam and make sure everything is ok. Thank you for asking Petco Pet Education Center, formerly Petcoach!
