My cat likes to play with the Breeze litter pellets. LOVES it. I never see her so excited to play. She doesn't play by herself that often. Aside from the gross factor of her batting litter all over the house, I don't want her to accidentally swallow it or something. She doesn't like balls, which is the only alternative I could think of. Any suggestions? She gets so excited I really want to find a safer alternative. Thank you in advance!
