> if your cat bites someone no one is responsible.

I had to double take there. Its because of the dangerous dogs act.

However there appears to be a nuance that if your cat is know to be a bitey little shit, and you let it out to into a situation where it might bite someone then you are responsible.

I think it gets murky if you are taking your animal into other people's property though. On your own property you have a duty of care to visitors (ie hidden man traps are not allowed, but clearly marked and cordoned off bottomless pits are)
