So today my kitten got his first distemper booster, giardia vaccine, feleuk test, 2nd deworming, etc etc and today he won't move! he looks like he is in the worst pain EVER....he won't hop around and won't eat or drink---only went to the litter box once to pee and is just kind of sitting there hunched over. He also squeals when I touch his shoulders where they injected him....is this normal or is he having a bad reaction to the vaccines??? help!
