Hey guys.

My cat just started acting really strange today. He has been sleeping most of the day. When I went to pet him, he growled at me especially when I touch his backside. He has now thrown up two times. He keeps sitting in a hunkered down position. The vet isn't open tomorrow and I really don't have the money to take him to the emergency hospital. Any suggestions?
He's most likely in pain, have you been to the vet in the meantime?
