I think Willy gets depressed sometimes. He'll go through spells, example, the last couple days he didn't get much outside time. It was very rainy and we were not home one night. Now for the past two days, he lays on the spare bed and won't greet my husband when he gets home from work and he wouldn't come get his kong before I left for work. He just lays in there, when I went to get him he acted all excited like he does when we come home, but he wouldn't get off the bed. I don't think he's sick. He's eating, drinking, playing, everything fine. He is a nibbler, he has to have his stuffie he carries around and nibbles on. It seems like a lot of the times he's stuck inside more than usual he gets like this. It's kind of weird. We've been giving him extra lovins and stuff, not sure what else to do except get outside. The sun is shining today, I'm going to go home and take them for an extra long walk.
