My cat had her first shots today (the vet figures she is around 8-9 months old) and she has been really sleepy since. She would not come when I called her and I found her curled up behind something sleeping. Is this a normal reaction to vaccines? She had rabies and distemper shots. I also noticed her nose was warm and dry. She did drink when she got home from the vet and she ate a little but now she isn't interested in food. I was told she will be back to normal tomorrow. Is this true?
