MidWest Homes for Pets Ferret Nation Large Hammock for Ferret Nation and Critter Nation Small Animal Cages, Measures 17L x 13W x 8H- inches

I have been using this since September and I am quite pleased with it.It is not, as I initially thought, a full tray (I didn't t read the description properly). Its a seres metal strips that clip on to your existing tray leaving a gap round the edge. I was initially worried about 'stinky things' getting stuck in the gap, but they do brush away quite easily and its survived a weekly hosing down without going rusty (early days I know). The reason it is 4 stars and not 5 it is a bit flimsy, was a bit of a pain to fit and I am a bit concerned about how on earth I will remove it without it breaking.Bottom line it does work! I have three young girls (rats) who are typical rats and can be a bit messy, the guard has significantly reduced the amount of bedding, food and other such lovely gifts they would normally attempt to throw on the floor. I previously had a Savic Rat Royale and the critter nation (with the guard fitted) is much cleaner

Unfortunately they don't make a cover for the upper shelf, which is what I wanted, so I took a chance and bought one anyway. Easily popped tray in and velcro'd up. Tucked corner in where hole to go to lower level is and hey presto! Done! Have just ordered a 2nd one.

I got this as a handy ladder for my rats for when they want to climb in and out of their high cage. Its really sturdy and the fabric sleeve is easy to remove and wash, as well as stable enough to stay attached and not slip off. My rats love it, running up and down, bouncing on it, and it remains firm and strong for them. Perfect as a platform or ladder for your pets to get around and have some free time!

It arrived quickly, when I opened it the front part was bent, so my dad straightened it out with hammer and put it together, apart from that its fine, you'll have to the tray and guard right back to get the door to remain shut, it goes the job

This is perfect I added Velcro at the bottom to go around the legs my ferrets no longer climb the cage and the walls are clean

It solves the issue somewhat. Litter still falls through the cracks. A bit of a pain to clean and rusts after a while. I wouldn't mind a sturdier solution.

I cannot believe all of the positive reviews for this product, it makes taking the trays out for cleaning (which you should all be doing with small animals periodically) near impossible because it's extends the width so that it catches as it comes out ... sometimes dragging everything else out with it and scratching the cage itself. It's flimsy and doesn't stop their urine from leaking if they are corner-wetters because it's not one-single piece but rather individual pieces slotted next to each other.The 'clips' if you can call them that, bend and deform with use (we gave it one week and they were already a mess).I am just disgusted at the quality of something purpose built for what is a great cage.

I wanted to find something that my rats could use during their out of cage time to leave the cage and go back inside. This is perfect! I have a Liberta Explorer Second Edition, not the Ferret Nation, but it fits perfectly against the outer rim of the cage. They can now come and go as they please!
