If you have a Critter Nation or a Ferret Nation cage and you allow your rats some free range time in the same area as their cage, this exterior ramp is a cool accessory to have. It is available from Ferret.com for an after shipping cost of somewhere close to $15 (prices and shipping tends to fluctuate, so check your cart for the actual price).
Our rats love the freedom of coming and going as they please and the ramp provides them access to their water bottles and litter boxes during play time, so I do not need to provide additional ones in the room. And when they are tired of running around and playing, they each make their way back into the cage on their own to snuggle in a hammock and take a nap.
Note that the description claims that the doors can be closed with the ramp in place. I do not believe that is the case. I can see no way to close the doors without damaging them or the ramp. Also, the description lists the compatible Ferret Nation cage models, but does not list any Critter Nation models. The Critter Nation is perfectly compatible with the ramp (and is even printed on the box the ramp comes in).
On an unrelated note, I found a little time to line the furniture pad I had on the floor of the Rat Room with leftover fleece and fleece remnants I had on hand. The result is this bright and cheerful rainbow floor mat. It is easy to clean, absorbant, soft and warm.
