Ricki Racer watched the Roomba pushing around her favorite toy, until ...it got swept up.
Take a pipe cleaner, wind around a pencil, like a spring, with the pointy ends tucked in (remove from pencil) toss and cats love to catch it midair and fetch.
Her Cheap kurly q toys, favored over pet store mice, etc. have lasted years. She does stretch them out now and then, and I just rewind into a spring.
She bats them around, then brings them to me, for me to toss, she :: leaves them on the bed, in the bathroom and by my feet if I am working.
