Our cat, Gus, is...energetic. With all the snow we've been having, he's had nowhere to roam and release that 6 month old kitty energy. Basically, he's a cooped up teenager and he's been taking it out on my furniture, my wrists and my ankles. Bad kitty!
We finally got smart and dug pathways through the snow in the backyard so that he could get to some trees. Now he spends a few hours outside everyday, climbing the trees and intently watching birds. Then he comes inside to collapse from the sheer exhaustion of all that mental stimulation.
