Lees Kritter Keeper, X-Large Rectangle w/Lid(Assorted colors)

Not really much larger than the large. It has taller sides but the actual floor area isnt that much larger. I dont think its worth the price.

Awesome size and design will work great for keeping crickets. the size is bigger than any other keeper I ever saw

When I received this critter keeper it had to long cracks. One down the side and the other down the corner and across the bottom. It still will work for what I need it for but if it was packaged better it probably would have prevented it from getting damaged.

Awesome..great price..and the exact color my daughter wanted..

Ive used these for a good many years to house a wide assortment of arthropods, small juvenile herps, etc. They also make very satisfactory nursery tanks for baby fishes if you dont overstock them, and use them in an area where the temperature doesnt fluctuate too much (their limited capacity offers limited protection against temp swings even if you use a low wattage heater with a thermostat.) In a fishroom with appropriate ambient temperatures, they make fine tanks for many tropical killifishes (the annual killies that inhabit temporary rain pools), and Betta breeding and female community tanks. These are made of clear hard polystyrene plastic (except the colored polystyrene lid). This material scratches easily, and readily cracks or breaks on sufficient impact. It degrades when exposed to UV light, and (much more slowly) to sunlight or bright natural light, thus these are unsuitable for long term use with UVB or full spectrum lighting. Several people have posted questions about using these to house garden snails. Both land and aquatic snails will eventually cover the sides with scratches from their tongues (radulas) as they lick at the sides when in feeding mode. Land snails will slowly scratch the sides by dragging their shells against the plastic. I use these to house kingsnakes past the hatchling stage; they are excellent for this purpose if properly furnished. The reptile heat mats sold for use with glass bottom aquaria may get hot enough to melt or warp the plastic. I use (and recommend) the seed/cutting starter heat mats that Amazon and many others sell, to heat these. If you cover these mats with 2 layers of household aluminum foil, position a single foil layer below the mat, and keep the mat slightly raised from the supporting surface (e.g. by putting the foil covered mat, with the Kritter Keepers on top of it, inside an appropriately sized plastic storage container, with the latter raised an inch or so off the supporting table), you can safely use these within a wide range of ambient temperatures without the use of a thermostat. Just make sure the snakes have an unheated floor area to cool off in. I unplug the heat mats when daytime ambient temperatures start reaching 80 degrees F. These mats use less than 40 watts and can heat 2 to 4 X-Large Kritter Keepers (depending on average ambient temperatures) when housing kingsnakes. The extra height is also a plus for keeping snakes, as it reduces the chances that an overeager snake will bite and attempt to constrict your hand when you try to drop a thawed out feeder animal into its cage. I would consider the X-Large Kritter Keeper unsuitable for keeping the following (some of which are pictured on the products printed enclosure!) It is really too small to adequately house pet rodents, such as the Phodopus Hamsters pictured, even if they are given an exercise wheel. As many reviewers have pointed out, any rodent that can reach the lid will quickly chew through the thin grid and escape. Laboratories use clear polycarbonate plastic cages to house mice and rats, but these have sturdy metal bar tops that are designed to prevent the occupants from reaching and chewing on the edges of the plastic. This product is also unsuitable as a long term enclosure for Green Anoles and other active, skittish, basking lizards; it is too small for these nervous, very active animals, and the UVB lighting they require will make the plastic brittle. Land hermit crabs will quickly scratch the plastic. Small feeder/pet roaches, small crickets, etc. will quickly escape if they crawl/jump to the lid. If you need a secure top (as when keeping snakes) but find the difficult to remove lid to be a nuisance, try releasing and slightly raising the lid from one corner first (all of my Kritter Keepers have one corner where the lid is easier to release), then releasing the lid from the remaining corners in succession. For use as a baby fish nursery or Betta tank, position the lid in an inverted position atop the clear plastic; this will prevent small fishes from jumping out, and spare you the hassle of working the lid off each time you feed the fishes, change their water, clean their filter, etc. Would NOT recommend using the small clear plastic panel door in the colored top; the small extensions that secure it when snapped fully shut are tiny and fragile, and will quickly snap/wear off after repeated closure. Thanks to Amazon for sending these to me in Lees original individual boxes within a larger shipping box; this gives these fragile items much better protection than they would have if they were stacked together in the same box. The extra cardboard is easily recycled.

This was a total life saver. After several mantis eggs hatching a few months ago I had them in different containers. Well out of nowhere and I didnt know another egg hatched and next think I knew I had all these babies in with bigger mantiss. So I took the larger ones out and I having another larger container was able to use this for the babies and then transferred them into the larger mesh container. However since so many of them didnt want to leave the container or were having a good time hanging on the lid, I left it in there for now. It was perfect for the new hatches. Great Value too!

my mice were able to jump up and walk on the underside of the lid. within 2 days they had chewed an escape hole in the mesh lid. All but the youngest were able to leave. apparently my pets were very athletic . I think the creature keeper would make a nice fish tank.

We use kritter keepers of various sizes in our menagerie for very young New Caledonian geckos, or as temporary housing for quarantine or cleaning. This particular size (x-large) I purchased for a 14 gram Crestie so I dont have to lug its Exo Terra to our gecko-sitter while were on vacation. With some cork bark, fake plants, and an adjustable bamboo branch it should be very comfy in here for a few days! They arent the most durable, but theyre lightweight and inexpensive and seem to both hold humidity well and provide good ventilation. The clear plastic also makes for great viewing, but could make a tiny lizard nervous so we will cover three sides in paper to provide more security. I would not keep an adult in here for more than the time it takes to clean its normal tank though - a larger plastic storage tub would be more appropriate. And I dont think this would work at all for a reptile that needs supplemental heating and lighting.

My nephew loved his gift.

Larger than the ones found in the pet store which works great for my crested gecko when cleaning his cage or traveling.
