I'm watching my daughters cat for the next week and he is very uncooperative in letting me give him his injections. This is new. He used to be ok about it but now he hisses, screams and scratches when I try to go near him. I had to cover him with a towel this morning to give him his shot but it was so stressful for him that he pooped.. stressful for me to and I got scratched up. I'm in tears here. In have no one to help me give him his injections.
