My babies love this thing! I put treats on the inside (usually yorkie yummies since they are so small) and I put one or two of the treat caps on. They can't get to the treats inside until they get through the cap. It's called "everlasting", but with 5 yorkies, I'd say "forever" is about 10-15 minutes! The great thing is, so far, they have not been able to destroy the actual blue (ball) part of the toy! I give it
