My cat is acting sick and in pain after vaccines. Is this normal?

Thank you for using Petco Pet Education Center, formerly Petcoach. I’m sorry Theo isn’t feeling well. This is not a normal vaccine reaction and Theo really needs to go to the vet ASAP. If it is not the vet who vaccinated him make sure to let them know he had a reaction so they can note in his chart and report it to the vaccine company. I hope Theo feels better soon.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Lily! Lily is likely having a reaction to the vaccines. If she has a fever she needs to see a veterinarian. When animals have fevers they do not want to eat. Your Vet, after their exam, will likely give her subcutaneous fluids and steroids. Once the fever and the reaction has subsided Lily will likely eat. There is nothing to do at home besides wait out the fever and that may take to long. Cats can not go more than 3 days with out eating or they get sicker. I hope this helps and I wish you and Lily the best!

It is certainly possible that he is having a vaccine reaction. If tomorrow morning he isn’t back to normal then I would call for a follow appointment with your veterinarian as soon as possible. They many need to give him some medication for nausea. Also, they will want to document the possible reaction so that next time he needs vaccinations he can be given medication ahead of time to prevent a reaction. Best of luck and I hope he improves soon. Thank you for using Pet Coach.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Milo. I agree, this does sound a bit excessive to me. I think if she is still acting this way in another 24 hours, I would take her back into the vet to get checked out again. I hope this helps!

I am so sorry that your cat Milo is ill following vaccines. These are classic signs for a vaccine reaction, and therefore I recommend having him seen by your vet right away. If you vet is currently not open, then I would consider taking him to your ER vet to make sure he is stable and ok. He will likely get medications (antihistamine +/- steroids) to help combat the reaction. I do hope that your pet Milo is able to make a full and speedy recovery. I would notify your vet about this as soon as you can so that precautions can be taken next year when he is due for his vaccine boosters to help prevent this from happening again. Best of luck and take care!

I'm so sorry that Noushmc isn't feeling well. Pain at the injection site and mild lethargy are very common with vaccinations and considered normal since the vaccination is stimulating the immune system. It usually lasts 1-2 days and will resolve on its own. If Nouschmc is not eating, is vomiting or it lasts more than 2 days, I would contact your veterinarian. Good luck! I hope she feels better soon and that was helpful. Thanks for using Petco Pet Education Center, formerly Petcoach.

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.
