3-Levels Easy Collapsible Ferret Chinchilla Sugar Glider Rats Mouse Animal Critter Chew-Proof Metal Carrier Travel Cage with Narrow 3/8-Inch Bar Spacing Easy to Setup No Tools Needed Easy Storage

Let me start by saying I love this cage even though it does have flaws. I am using it to house my two female rats. I’ve waited a month to write my review because that is plenty of time for my mischievous girls to poke around every square inch looking for their great escape as well as nibble every bar to find any weak spots.When I got the cage I was very nervous because the bars are extremely flimsy and a few were bent out of place. As I set it up I noticed it doesn’t line up very well and there were some gaps that seemed pretty large to me. I hadn’t picked up my two girls yet so I wasn’t sure if these gaps would be large enough to escape and I was worried that they would be able to push the bars and escape. Well I bent the bars back into place and attached a small clip to the gate where the largest gap is. I keep that clip on always because they can definitely fit through that space with little effort. Fast forward a month later, I haven’t had a single successful escape effort. They haven’t even been able to open the doors by themselves, which was a problem with my previous cage and ratties.Now for the cage itself. The levels were the same cheap metal and they were both bent out of shape, I bent them back and haven’t had an issue with them. My ratties don’t like the ramps and kept throwing them into the bottom of the cage so I decided to take them out and free up a little more space for their toys. The levels aren’t very high and my rats just bounce from level to level.The cage isn’t very large although it does take up more than its fair share of my bedroom. Because of its smaller size my rats get bored fairly quickly and start chewing the bars. Im worried that with enough time and effort they may be able to gnaw through the bars with their mega chompers, so far though they havent even made a dent in the paint. To help with the chewing I fill their cage with dollar store bins, wood chews, and cardboard box toys that I make. The cage is just barely large enough for it and I want to get them a bigger cage in the future, but this is just about the perfect starter cage for them. I change out their toys every time I clean the cage so it’s a little different area to explore each time. Cleaning the cage is very easy with the pull out tray I just pull out the tray, vacuum up the litter, give it a quick wipe down and we’re good to go. I took pictures without any fleece in the cage so you can get a picture of what the levels and floor look like. Overall I am very pleased with this purchase and I think it’s a great little cage even though the materials are cheap and you might have to readjust some things to make it work for you, it’s definitely worth the price, and my girls love it.
