Lees Kritter Keeper with Lid Small Pet Carriers at Pet Mountain

On June 12, 2013:
I needed a quarantine tank for new fish to keep from unncessarily spreading disease before they are put in the main tank, so I was looking for something inexpensive. I love it! It holds approximately 4.5 gallons and is just right for sick fish (I treat them in there) or a new fish or two that needs to be quarantined. The lid snaps on and off easily, there is a hole for your filter pump line and heater, and a trap door on the top so you can reach in to feed without removing the top. Minimal disturbance to the fish! Its working wonderfully so far. I would recommend it!

I use them for all sorts of baby geckos. I'm able to spray heavily but they still dry out in between so I don't get mold. Great for geckos like baby gargoyles that need to be housed individually too!

My department owns dozens of these in all sizes and they're used to isolate and maintain marine invertebrates of all types in our flowing natural seawater system. The only occasional glitch is that some strong and agile crabs are able to pop the lid open and escape. Otherwise, they're durable and long-lasting, even when spending their time completely immersed in seawater for weeks or months. The solution to the escape hatch issue is rubber bands. Otherwise, my classrooms can't do without 'em!

The wet lab in my department uses these super handy critter keepers by the dozens, mostly for isolating and maintaining marine invertebrates and small fish in our flowing natural seawater system. We probably own a hundred of them or more. They work great about 95% of the time, except that the small window hatch doesn't always stay tightly closed and some crafty (and strong) critters like our local green crabs (Carcinus maenus) are able to open them sometimes, and escape. Otherwise, they're tough, durable, and easy to clean. The polycarbonate casing stays fairly clear for years, even totally immersed in seawater. The solution to the escape hatch problem is rubber bands. I give them 4 stars only because of that glitch. Otherwise they are an indispensable tool in my labs.

Price is good, prompt delivery. The lids are a bit on the flimsy side. Thanks.

So cute! We got some from the OC fair with goldfish and I got the idea to give them out for our Luau to the kids as party favors. The kids loved it.

I gave these out at a residence hall program, and everyone loved it! best price i could find anywhere by far.

Love the kritter keepers. They're great for my bettas who are much happier in their own homes rather than sharing a divided 10 gallon!

These are great for housing small animals, from birds to rodents to reptiles. They're easy to clean and relatively sturdy. Great product!

Great for breeder boxes- highly recommended! Easily stacked as well.

I own two of these cages, one of them is a medium and one extra large. The medium was the first cage I brought and I love the product already, but I felt it wasn't big enough, so I brought the largest one. It was bigger than expected and my hamster love the cage. When I found out Pet Mountain was selling these XL were so cheap, I brought one. It was packaged nicely. I love the size and the price. Since the cage is so big, I'm planning on buying another hamster. I will do business again with this site for sure!

I raise sugar gliders and ship all over the US and I put these in a cat carrier and they give the proper ventilation for these little guys with plenty of room to move around.

I raise Killifish. These are perfect size breeding tanks. At these prices you can't go wrong!!!

These are wonderful sized containers for many types of small pets and very versatile. They are a must have for trips to the pet store to bring home a small animal (rodent, reptile, etc..) safely rather than in a box! For some species, they can be a starter set for a home environment tho all animals should be given as much room as possible for a long healthy life. (NOT recommended for a rodent starter set!) They are great for quick transport on trips or for temp housing while cleaning the pets main home. They are easily accessible to put the animal or food in container and secure to keep them inside tho the plastic snap up lid should ALWAYS be extra secured just in case...by tape or a heavy object and stabilized.

We use these plastic keepers for all kinds of "stuff", both living and for things on display.
We give them to all of the second grade class rooms in our school district with Kritters to keep for the school year.
They are economical, and very useful.

L or XL Kritter Keepers are perfect for a boy mouse or a pregnant momma. Any size is great for transportation or temporary housing as well. Much cheaper than buying an aquarium and a lid and much more worth it. The lids are nice and secure, and cleaning is a snap. Lightweight for those who, for whatever reason, may have a hard time lifting things. I've heard of mice and hamsters chewing through but have never personally had a problem. I love these!

I've had rats and gerbils for years, and this is the only carrier I use. Its solid sides block drafts in cooler weather, and it's a cinch to clean. This is the best price I've found anywhere, too.

We use these boxes to show our rats in at the NIRO Show in Illinois every year. They are the perfect size for the short time the rats are in them. Quality made!
