I know Frisk & Khaith would stay with my parents.. as both adore them.
Norri would probably be taken by my parents, also, as he isn't very demanding.
Don, on the other hand, needs alot of attention. He doesn't really like anyone else but me.. so I don't know. :/ Maybe my sister could get him to like her.
The rats & rodents would go to my sister, but my dad promised me he could take care of them if he needed to.
The fish. Well. I don't even know. My sister has managed to kill just about every fish under her care(has bad luck with them). Maybe my dad could handle them.
