What a great Idea! Using an old dresser to hide away your nasty litterbox. Cat goes in through the side (pet door) and when the front is closed it looks like a dresser. Also my dog will not be able to get in it and snack on kitty cookies.
Here's a cool DIY idea for a cat enrichment toy. Glue together a group of toilet paper rolls inside a tissue box and randomly fill the tubes with treats. Your cat will be stimulated when they "hunt" for a treat. So simple and inexpensive.
