What's wrong with my dad?!?

I fear for you hon. It sounds like your dad is having some mental issues. For whatever reason, it happens. It happened to my son's father. I think it IS a good decision on your part not to be around him right now. Have you discussed this with your mother? Also, perhaps you should talk to someone at the local humane society about all these animals your dad is accumulating. Most cities/towns have regulations on how many you can have within the city limits. I know it's kinda' tattling on your dad but it is for the welfare of the animals. Good luck and be careful, dear.
