I'd hate to take his rock away. He's had it for almost 20 years. It's got coco husk all over it now. He loves that drift bark too!!! But after one sniff, wild man, watch out!!! Maybe it perked him up a bit. Ever since he's been in Wisconsin(10 years) he hasn't been eating well durring winter. Maybe 3 times nov to April. Maybe he'll eat monthy now. Maybe a good thing, I hear they eat less the older they get.
