Great litter pan for small rabbits, too small for large rabbits. Good construction and value for price. I prefer the plastic grid for rabbit feet. Not sure why there is a rating for absorbency, this is a litter pan, you don't want it to be absorbent! LOL Most rabbit scat falls through the grate. The 2 high sides are great for limiting spray as rabbits like to pee against the side of walls. The plastic attachment bolts work well with X-pens. I like how the pan pops out of the bolts that can stabilize it to prevent it from moving around. This latching set-up works great with X-pens but would not so much with rabbit wire, chicken wire, pet-store small animal cages, or hutches using wire. However, I caution again making sure to buy a pan big enough for your rabbit! :) I will need a larger size than this.The quality and function are great, and have stood up to the insatiable chewing of the young bunny we have. Easy to clean.The only downside is as our bunny has grown he often turns sideways and pees right over the side. We put a rubber mat under it.This looks like a nice litter box for a small pet (hamster, rat, etc) it is way too small for a rabbit.Great litter box. I do think the holes in the grate part are too large for a baby guinea like we currently have, but feel when it grows it will be fine. Right now we keep the grate off and use paper bedding. We followed guidance we read online about how to get them to use the litter box (making it feel like a safe place, dark, keep their hay there). And it has worked great. A few stray droppings, but most is in the litter box. Also it's only day one. There's been a remarkable difference in where the guinea does its business. It's amazing.This would be good if it was bigger. It is the size of my Holland lop. It doesn’t give them room to turn and move to wat their hay and use the litter box.The little plastic bolts that hold the litter box to the cage pop off easily. My rabbit is a bit rambunctious and takes his off all of the time. If the bolts held better this would be a great product.Although rabbits tend to want to dump over their litter box, the side anchors, which fasten to the cage, keeps the litter box in place, usually until it's about time to clean their box. I'm not sure why rabbits like to tump over things, but it's pretty universal, from bowls of berries to toys to litter boxes. The only problem I've found with the litter box, is my rabbits won't tolerate the grill on top. I eventually just removed it due to them continually tossing it aside. Other than that, it's a functional litter box.Could be larger for a bunny, it’s not that deep so poop didn’t just fall through grates into box. Daily clean up... also a pain to take on and off cage to clean regularly.
