Hi, My 8 month old cat had her second vaccination at the vets yesterday. She was fine when she came home, couple of hours later she was very sleepy, she seems to be walking stiffly and not eating. When I picked her up to put her on my bed for the night so I could keep an eye on her, she growled, cried and hissed at me ??, normally running around playing, is this normal? She was fine with her first set if jabs!! Currently under my bed refusing to come out, very worried about my kitty??
