Have been taking my cat to the vet for while trying to help with her chronic gum issues. They are pretty bad...He just suggested some injections today (Tues), and I agreed without really asking what they were (not smart). Looked at the invoice when I got home (pretty steep) and saw that she was given convenia, and and an injection of steroids. Not knowing what that was; I looked it up on the internet, and came to this thread. Now i am concerned she may have an adverse reaction. I am going out of town on Sat, and will be keeping a close eye on her until then. Will post any adverse reactions if they occur.
