Adopted cat sick after vaccine: is it stress or vaccine reaction?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Mediumhair | Male | unneutered

I recently adopted a cat that was living by a friends restaurant. He's 6 months old. He was with him mother and brother. After a couple of days he got along with resident cat. After vaccine he stopped eating, started vomiting, diarrhea, watery eyes. Is this because of the vaccine or because he misses his family?

Baloo may have had a mild vaccine reaction causing the symptoms. I'm sure he is missing his family but give him some time and he should recover and settle in with you. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Baloo.
