Simba has taken to digging out socks from the laundry pile now. I'm not sure where he picked that up from, since Nala doesn't do it anymore. I'll find a sock on the ground here or there while walking through the house. Occasionally I'll catch him sniffing through the laundry baskets probably looking for a sock to nab. I even caught him once with a sock dangling out of his mouth looking at me like it was time to play with a new toy he found.
I don't think he's eaten any yet, but I guess it's time to start closing the closet door again until I can get him to stop going after socks.
