the older ferret: he may not be the energizer bunny

My ferrets have always come when I call them. So I guess I should not have been surprised when I challenged Buddy to follow me around the house and he did. Both ferrets have supervised out of cage time every evening for about an hour. Buddy, being the older ferret that he his, would mosey a short while then head back to the hammock. Knowing how important it is for him to keep moving, the two of us do several laps around the house together. My first few attempts were trying as I coaxed him to keep going; at every pass of the cage, he tried to sneak in. Now it is a routine — I walk and he follows... slowly. I’m just happy he will keep going and going and going...
