” I am a small breeder and have been looking for a replacement to the Second Nature litter box for years….. Search is over!!!! I use the large size for my puppies and my adults will use it too. I’d love to see an extra large size for multi-dog households! Well made out of sturdy plastic; chew proof and tip proof. Perfection!!!! Love the seller,, I have linked to her for all my puppy families. Thank you from the bottom of my heart. This was a game changer for me! Just ordered three more.”
