Pardon the pun... I have three cats and it gets expensive to feed them all their various foods they need to eat, plus all the cat litter; it really adds up. When it comes to buying them a litter box, I refuse to pay 20+ bucks for a covered pan and even the non-covered ones can cost some money as well. My cats are pretty big so the regular boxes they have in the cat section are quite small for them. I go to the storage section of the grocery store and find regular plastic storage boxes for less than 7 bucks. Sterilite is a good brand. I saw one recently on sale for $6.89. Here is a link for the kind of box I am thinking of:Please Log In to view this link! If you really want covered boxes, try cutting a hole in a tall cardboard box and then turning it upside down over the litter box. The cat won't know the difference and you can save some money. Heck, you could even cover it with contact paper or wallpaper to make it look decorative if you want. So you see, it does pay to think out of the box!
