I have had the Littermaid for a while now, and it works for our two cats and frequent foster kittens. I love it! We don’t have the super high end one, just the Littermaid Elite, and I have never bought new containers for it. I use plastic grocery bags to line the plastic boxes, and I duct tape around the top inside and outside of the plastic box so that the plastic doesn’t tear. Lasts forever! Also, you can buy “activated carbon” from ebay in big quantities, and I tie that into little sachets to use in the litter container instead of their expensive carbon packets. It’s a huge savings, and we go through far less litter because of the littermaid. Our cats love it, too!
Clementine used to have an attitude problem where if the litterbox wasn’t totally pristine, she wouldn’t cover up her poop. Well, in a small apt., this is a problem! So she’d go in there and make the biggest, stinkiest pile of poo you can imagine and then leave it, as a protest! As soon as we’d scoop the litterbox, she’d stop doing it. It got our attention, all right! Now, she never does this. They love the Littermaid. I got mine at a resale store, new in the box, for $10, but if it broke now I’d buy a new one because of the money we save on litter.
