egg-cersizer in the cage a few times a week and it gets batted around like a soccer ball. Bertie and Pinniped would immediately face off like opposing teams. Even now, Pinni comes running over and noses it over as soon as I place it on the floor.
What I find entertaining is where the egg-cersizer winds up at the end of the day. After it's emptied, I find it stuffed in a corner or wedged behind the brick under the water bottle. My favorite is the one time it was slam-dunked into the nearly-empty food dish. How did they manage that?
Once the girls wedge it into these spots could they ever get the egg out again? The spot behind the water bottle isn't very accessible. The egg-cersizer is usually empty when I find it in jammed in a corner, so there's not a whole lot of motivation to dig it out. Was it tucked out of the way on purpose? Perhaps they were putting their toy away, the game having ended when it ran out of cranberries. I suspect it's sheer luck that it gets wedged in these spots after it's empty. On the other hand, knowing guinea pigs, it's more likely a message for me to refill it.
