Cage expansion

[becky20]

Hello everyone,
I was wondering if anyone knows if the WARE Clean Living Add-A-Level Small Animal Cage Expander sold at petco and petsmart are compatible with other cage brands or just ware cages? If it's not compatible what are some ideas on expanding my chins cage?

What kind of cage do you have? I'm guessing that expander is only compatible with the Ware Clean Living series of cages.
