I have not had my cats vaccinated in years. My late kitty Taz, after vaccination swelled up so large and I'm not kidding on this, I thought he was going to pop. It was the scariest thing I've ever seen. The vet said...it happens. We get the pup vaccinated only because he is outside sometimes and goes to the dog park. I only vaccinate what is needed for his license.

Please update us on Shadow's progress! I'll keep praying.
