My neighbor just got a cat that came from a home where the husband killed his wife , his 4 year old son and then himself. Then the girls mom took the cat but could not take care of him and that's when my friend took him. This has all happened in a 2 -3 week period. The other problem is she had plans to go away and really could not cancel them. She was with him for 1 night. So I am going over a few times a day to brush him and play with him. I was sitting there talking to him and telling him I know this is very hard for him. He responds to that but what more can I do? He does get upset very easily and will swat at you or try to bite. He is declawed except for his dew claw. I came home and washed my hands up and found a few marks on me. My cats have been very good when I come back home. I wash my hands right away but his smell is still on me but my guys have been great. Any help would be appreciated!!!
