Do you know the specifics on the vaccines? Some have more side affects than others.
Also, in most cases there is no difference between the Three Year Rabies and One Year Rabies vaccine
It's generally the exact same vaccine, it's just the labeling is what counts. Where I live, it's the same vaccine for the 1 year and 3 year, but you get it as- initial vaccine, booster 1 year later then every 3 years you get boosted... it just depends where you live though.
Your cat should really start acting more normal by tomorrow, if not call your vet asap!
