Bad form.
I've posted this before when this has popped up in the past. Life happens and unexpectedly. I never planned to get divorced, it just happened and as a result I had to rehome pets because I couldn't take them. I didn't ask for the divorce, I didn't want the divorce, but there I was being asked to leave my home. I had never thought that I would have to do that. So I'm a re-homer, bring on the nasty emails to me
