Can anyone tell me why Mitzi keeps taking bits of her food and hiding it all over the house? She keeps trying to bury bits in our bed between the pillows and anywhere else she can. She puts bits of her chicken on the floor and tries to cover it , but the floor doesn't move! She is there for ages trying to bury it without success. It's cute to watch her, but with spring on the way, I am worried about getting insect visitors because of her stashes I haven't found. Can I stop her doing this? Or do I just have to let her?
