Hi and thank you for clicking on this post! Currently I have 14 rats, 12 are babies and two are adults. I have two cages which seperate the boys from the girls (7 in each). The babies had a very sudden growth spurt and are in need of a bigger cage. Ive been looking into them but im not sure of which to buy. Right now i have them in a Rat Manor from Petco. Any Recommendations are appreciated!
