Large Triangular Litter Pan
All of them have had their litter pans upgraded to larger ones. I use two types. One of them is the Marukan MR-314.
Here’s what it looks like:

I know this is blur, but you still can see the grids of the Litter Pan

The add on hooks are taped to the bottom of the Litter Pan when you purchase it. All you need to do is to remove it before you use it.

What we like about the MR-314:
It is a lot bigger and deeper compared to the AB Seton (GEX) litter pans and it’s still triangular in shape. It is flexible such that it allows us to choose if we want to secure the pan to the cage/playpen by screwing it to the grids or by hooking it on.
Being bigger in capacity, it means that the litter pan will easily last two rabbits a day or two before we clear the litter pan without overflowing. Bun-buns are less likely to get dirty paws or butt when the litter pan has filled too fast. Also, we can safely put in more layers of newspapers and bedding without worrying about having lesser space in the tray for the poop and still be able to soak up the pee. Also, with a deeper tray, their fur is less likely to stick through the grill onto the pee and poo.
Overall, the litter pan is easy to clean as well. The grill is easy to remove as well for cleaning.
What we didn’t quite like:
The downside about it is that you can’t choose to use the hooks to hook and screw the litter pan to the grids of the cage/playpen at the same time. It’s either one or the other. We’ve got bunnies that like to pull the litter pan, so additional security could help. However, we solved that by drilling holes to allow us to use wires to help secure the pan.
