One time I ran from my bed to the kitchen just to see what BUDDIE would do, and he chased me, so then I ran to the closet, he chased me again. So I thought I would reverse the rolls and ran towards him, he didn’t move, so I tickled his face, that gets him excited, and I said… I’m gonna get you, then u tickled his paw, and he ran, I chased him around my appartment saying I’m gonna get you, and if he stops running from me, I’ll take off running and he’ll chase me. Its great exercise for them. Also when I just stand up and stay there, he circles my feet, round and round, changing directions, hopping threw my legs. When he stops, I say.. I’m gonna get you, tickle his paw till he runs, and the chase is on, while he’s running from me he’s hopping why up in the air doing little twists. That’s a happy/playfull sign. He never runs out of food, and he’s getting a bit fat, so I know this playtime excersize is good for him.
