But they actually have many other useful purposes. You can: 1) Cut an X in the top of each ball and put them on the bottoms of chair legs to cut down on noise and floor scuffs. If you don't have scuffable floors, many schools take donations for just this purpose. 2) Donate them to a local nursing home for use on residents' walkers. They make the walkers easier to push around for people who aren't strong enough to lift them. 3) Hang one on string from the garage roof to help you park without running into things. When it touches the windshield or rear window, you know it's time to stop. 4) Keep certain types of gnats or flies away from you when you are outdoors.

Ask your veterinarian for advice on alternative toys. ===================== Comments: The car door trick only works with cars that have vacuum operated locks, and actually can do damage to the vacuum system if done repeatedly. Vacuum operated locks can be found on older jaguars, and I believe some Mercedes.
