Gerbil Potty

I have two gerbils named Acorn and Daisy. I have CritterTrail One and Two and one of these potties. Mine is blue and yellow. I put it in the petting zone in CritterTrail One because that was were the gerbils always used the bathroom. Now they use this potty. But they also sleep and eat in it. That's gross. They also throw a lot of the litter out of the potty. I only gave it four stars because Acorn chews up the yellow part on top. I wish they had made that out of something gerbils can't chew up. (If there is anything they can't chew.)More detail ...

Super Hamster Wheel

This hamster wheel was perfect! It fit my Crittertrail hamster cage like a charm and it was much quieter than my old wheel. I loved this wheel and so did my hamster.More detail ...

Great expansion kit!

This is a great expansion for any cage! It does not come with instructions but if you look at one of the pieces it has extra plastic rings in the middle of it put this in the hole you are adding the expansion on too take the J shaped piece and from inside the cage with a O ring on it snap them together (WARNING) it will be hard to get them back apart without taking the top of the cage off and alittle work. But the top of the lookout comes off and allows you to have even easier access to play with your pet. As bad as a pun as it is I really wanted to say play with your little critters LOL. Oh and if you try to put it on the side of the cage OFCOURSE you are going to have issues with keeping it upright. it does not really attach that way it is mean to the top or for adding into a more stable section of a expansion.More detail ...

Great Product

I use these for each of my male hamsters (they have seperate cages). I got them these when they were just babies so they grew up with it. They only use it for #1 and still go #2 in the cage but really that's where the smell is coming from. I don't actually scoop anything cause it doesn't work but I just dump the whole thing out and refill it. It's pretty sturdy and i haven't had any parts break. Start your animals off with this early and it's great for keeping the cages smell to a minimum.More detail ...
