Stopped at pet smart on the way home and picked up more little foam balls for Snoopy. They only had one package of the soccer balls left, so I got that, and a package of foam golf ball looking things.
Well, I went with the golf balls first and tossed them out - no interest at first, but a few minutes ago I could hear the unmistakable sound of a horse galloping through the entry hall, which means Snoopy is having a high old time with them.
