Sounds like Dad has some control issues... he needs to be in control. Aunt won't go into a nursing home because of her cat, he takes her cat and doesn't tell her. Now he decides to dump the pour soul in the middle of lord knows where?!

Your aunt must be worried sick about her "missing" cat. Have you spoken to her?? What if she gets really sick because her cat is missing?!

Can you get dad to tell you where in Grand Forks he dropped off the cat?? That poor thing must be so confused. Why would he do that??? I mean, unless he's got some deep seeded issues and doesn't care if the cat lives or dies. That's just inhumane.
