Jedi has this one red rubber ball that is pretty much designed to look like these 6 sided patterns connecting into an orb. He goes NUTZ over it. It is the only toy, he stalks, pounces, barks, growls, snorts, and overall tears into.
It is pretty light, so when he pounces his nose hits it half the time and it rolls out of reach. This just makes him MORE determined to catch that rascally ball. I laugh my head off, to the point he has stopped to stare at me laughing a few times, to figure out what is happening.
