I'm going to sound like an informercial for a second. Are you sick of sweeping excessive litter around the litter box? Would you like to hid the contents of the litter box? Well, you need to make yourself a top-entry litter box. The price is unbeatable. This DIY litter box can be yours for only $5 to $10. Similar top-entry litter boxes sell online for close to $40. All you need to make your DIY top-entry litter box is a storage container, something for cutting plastic and some time (about 10 minutes). OK, infomercial over.
