Lee's Kritter Keeper Rectangle with Lid for Small Animals, Small Size

I use these to transport mice and small mammals. They work great for transport, temporary housing while cleaning, and as show boxes. They clean and disinfect easily and the plastic is scratch resistant for being wiped down. I have some that I have been using for 5 years and they still look great.

Purchased the large size (3 gallons) and they make the perfect home for my bettas. Nice that they have a lid considering they can be jumpers, just wish the large size had handles for convenience when pulling the lid off, but not a big deal. I have a baby betta in one that I do cleanings on every 2 days or so and even with my sloshing of the gravel and scrubbing down the sides, there's minimal scratching to the walls. I have a betta log, two log decorations, an Aqueon 50 watt heater, moss ball, almost a full bag of gravel, and 4 live plants in mine and there's still plenty of room for my baby female betta to swim around. For my adult male bettas, I just go with one medium sized cave decoration instead of the two and they've got plenty of room. I've added a picture for a visual idea of what can fit.

I use these hammocks for foster kittens and while the size, fabric quality and metal clips are great- the kittens chewed through the straps within a day. I prefer the heavy nylon straps and these are a thin grow-grain ribbon. For Ferrets it may be fine.

I breed Bettas and the Mini is perfect for keeping unsold fry in once they become too aggressive to be in my 25 G with their siblings. I also use them as a quarantine tank for when my Bettas are sick mostly for my females as they bunk together. For permanent Betta housing I recommend the Large, everything else is too cramped for a Betta. These are very easy to maintain, and heat and very cheap.

These tanks are great and a must have no matter what kind of pet you have. I have used these for almost everything even non living things. I have used them for brooding baby birds, housing snakes temporarily, bird travel cages, to move fish from one tank to another during cleaning and most of all for rasing moths and butterflies from caterpillars. Some species like the sphinx moths I fill with soil because they need to burrow to pupate. It's nice they come in different sizes. I prefer the largest and second largest for what I do. I have even used them to soak and disinfect bowls in bleach. Just wonderfully handy little keepers. I'd give it a 10 if I could. I posted one of my How To videos for raising moths and butterflies in these clear boxes. Double click to open in its own window and see more related uses for it. I love that these come in different colors too that are so bright.
