These additions are sooooo neat!

You will love it and your pet will too!!

Made of 1/2" x 1" welded wire. The cages are made of 16 gauge welded wire and will last a very long time if not left outside to rust! This unit sets directly on top of a 20 gallon long aquarium . No assembly required. There is a long ramp going up to the first level. I use very strong door latches. There is no way your pet will escape this cage unless you leave the door open. Plus your critter will be safe from your cat or dog too!!

This unit is 30 1/2" long x 13" wide by 14" tall.. 2" is used for overlapping the outside of the aquarium. It sets directly on top of the aquarium. You can let me know if you need a certain size door to accomodate your wheel.

This cage is brand new never used. There is hard plastic door guard around the raw edges to prevent you from getting scratched and also prevent your pet from getting scratched. I think you will be very pleased. This cage was designed by an experienced pet owner. It is put together with Jclips and is completely ready to use when you receive it. No assembly upon arrival.

Perfect size for my rat and her new friend that will be joining us soon! Well-made, sturdy, and plenty of space for toys and accessories. I love how large the door opening is. Shipping was prompt. Thanks so much!

Topper is exactly as described, well made, and I think it’s prettier in person. We have two VERY happy gerbils!
