Popped!
We bought a "Wall-E" ball for the kids earlier this year so they would have something to play with. We've tried very hard to keep it away from Tosca, thinking that she would quickly destroy it.
Today, Tracy bought a R10 (throw-away) ball for Tosca while she was at the store this morning. We placed bets on how long it would take before it popped. I said two hours, Tracy said 1.75 hours, Catherine said five minutes, and Mark said two minutes.
Tosca went nuts: running chasing, jumping. It took about 1.5 minutes! She couldn't bite the ball, but she pinned it against the wall of the house, and pop! That was it.
It was fun while it lasted, and we all had a good laugh.
