Viciously. My dog is bleeding (not life-threatening, and I treated her at home) and our cat lost a few nails and is also bleeding (not life-threatening as well).
I am at my wits end with this. This cat is very dominant and has acted out for the past three years (mostly because H lives with us now). We've tried to find him a home before, and decided to keep him, and now he's getting worse.
We've tried everything - behavioral therapies, medications, herbal remedies, etc. to keep his behavior in line. The reality is that he's only sweet to me, and hisses at everyone else. He's bit a few of my friends and scratched others.
I really don't know what to do anymore. My mother was going to take him in when we moved, but now she won't, because she has a dog, and we don't want to put that dog at risk, either. I'm trying a ton of rescue places, again, but they're all at full capacity.

I has a sad.
ETA: I should add that the attack was completely unprovoked.
