If you have a larger cat, then you need a larger litter box too. You probably wouldn’t be happy if your family asked you to squash into a tiny box just to go into the bathroom. Most importantly, though, your feline friend will need to fit in their litter box. Your kitty also requires something easy to get in and out of. Your pet will need enough litter so that they can dig in to cover up their mess. There are a few things that all large cats want from their litter boxes. If they're big, then the litter box needs to be large too, so that they have 'room to manouevre'! So far, they are working well for me and my kitties and I do recommend them.To state the obvious, if your cat is a large breed (maybe a Maine Coon or a Bengal, or just a big fella!) then they will need on of the largest cat litter box options that you can find. They have gone up $10 in price from when I first started looking at them, but my cats are happy and so I am happy and bought the rest of what I needed to replace the old ones that were left (before the price goes up any higher). I have thus replaced them with these due to the high sides. I do have 2 cat boxes that measure slightly bigger than these at the bottom, but they are low-sided and we all know what that means.

If they aren't big enough, you may want to consider making your own from plastic storage totes.

These are the largest high-sided boxes I have found, and I have looked far and wide. After looking at my 16 pounder maneuvering around in the new box, I wonder how he ever managed to fit in the old one! Now, he has room to comfortably turn around and scratch. If you need to move it later, pick it up from the bottom and not the sides. I would suggest you already have it where you want to place it and then fill it up. These boxes take a lot of litter, so I can see that picking them up by the lips of the box would make it likely to break from the weight. Also, there are some reviews that the sides or lips of the box have broken when they picked them up. One other review said it took them 40 pounds for 2 boxes, so you will want to make sure you have enough litter. I put in one 19 pound box of litter and it measured just under 2 inches in litter depth. There is a minimum fill line in the box, which is nice. They will even come downstairs to use the new one rather than the old ones upstairs. I did place it next to the old one to compare usage and the old one is hardly used. I bought several of these that I am going to be setting up, but the first one that I have set up is the most used box in the house already. This is the original very large litterbox, which I merely enclosed in the furniture I think that helped the cats accept it so quickly. But the directions are good, and it worked! The second photo shows the doors open for servicing, with the liner flap down. All in all, highly satisfied! As people have noted, it's a little tricky to put together, like a lot of furniture that comes in a flat box. Also I don't feel I have to apologize to visitors for the prominent litterbox (I don't have many options for location). However it is a vast improvement over 'dust everywhere', and the cats like it. But they did start using it the same day! As you can see from the first (unretouched) photo, it is a nice looking piece of furniture and contains the litter dust very well, though not completely.

My cats took to this immediately - well, after a period of investigation. I've had great experience with cat furniture from Refined Feline and this is no exception. Attractive and most importantly - accepted by my cats
