I recently got a great new toy as a gift available through Omaha Vaccine Catalog and Petopia. It's called the "Wiggly Giggly." proof and durable! >>>>>>.

I shop at Ohama Vaccine also.
I will have to check out the Wiggly Giggly.

I couldn't believe the stuff, I found in my males poop when he was a pup.
(I thought my yard was puppy proof)
Bird seed, corn, little rocks, plastic from
a large planter, leaves, fur and feathers.
I am glad he grew out of eating rocks.
I could have had one large vet bill.
