Yep, me too, 2 many !
We have about 20 and still have some new ones that Ruby received in a gift exchange. We had toys coming out of our eye balls and the pups had a blast with them. We cleaned out some old ones that they had no interest in and replaced them with some of the new ones.
Ruby is the only one who plays with them on a regular basis. She will empty the entire basket, I clean them and 10 mins later they are scattered around the house again.
