Comments: I'm really glad I bought this product, along with the Critter Litter Deodorizing Potty Pearls. It makes cleaning my rats' cage so much easier because with the two combined, they don't go to the bathroom anywhere else.

As for the locks, this product does have two hook on the back, that face downward. It works perfectly with the cage that I have, because at the exact height of the hooks, my cage has a horizontal bar that they can easily attach to. Making it so the litter pan can not be tipped over or moved. But, if your cage has all horizontal bars, or not one at the right height, than yeah, there are no 'lock' per say on this product. Still, I would give it a try because it's a really great product. Very sturdy and easy to clean.

Comments: I've had one of these litter pans before, and I mistakenly purchased one again. The "locks" are just hooks that don't secure the pan to the cage. I was disappointed with this purchase.

Comments: This litter box is big enough for my rats to be comfortable using. It is good at keeping mess down, that's for sure! My only complaint is the little feet on the back to attack it to the wall don't work on my critter nation. The bars are horizontal and too small to fit in between them. It would work better for something with 1inch +/- rather than my half inch bars.

Comments: This is a great high back litter box. My rabbits are large so they need a large pan. However the description indicates locks - there are none (which is the main reason I purchased these). But if the locks aren't important, then these are a great deal!

Comments: This is a quality product. Heavy duty plastic doesn't tip when the guinea pigs crawl in. easy to clean. I would recommend this product to anyone who is trying to litter pan train their small pet.
