At the beginning of the month I noticed Precious was ripping out his fur and had a huge scab on his back. Well I made an appointment for the vet (which is for next month.. go figure). Well over the month my wife left with the other kitten. Well today I look and there is no scab and the fur is growing back. Could something like this happen from stress or something else? Since she left hes seem happier and getting his playfulness back. He was lonely for a bit there But I got a new little girl (Lily) and they play together now. But could stress cause him to rip out fur like that?
