I have 10 rats... 5 males and 5 females. They currently live in 5 cages (a pair per cage).?

I had the same problem but all you have to do is buy the Ferret Nation cage 142 (2 levels) Then you can separate the 2 levels and each level can hold up to 9 rats! So you only have one cage. If you are confused at what I'm telling you or have any questions, please feel free to email me ok?
