We have 3 new rats (only 3 toral at the moment). I dug out our cages we used in the past today and ordering new fleece sets/hammocks Wednesday, which got me thinking... I really want more rats. In the past we had 14 rats... and I loved having all the different personalities and loved seeing them piled into their hammocks.So we talked and agreed to expand our rat family at some point. But here is the question what is the perfect number? We have 2 cages we plan to us (male for one and one for female or combo spayed/neutered colony). Cage one is a double CN that could be a triple as I have the piece for a full triple cage two is a Martin's ferret penthouse that was custom ordered to have rat safe wire spacing. Anyone have multiple rats that has large cages have any advice?Next I want to learn to sew my own hammocks, any advice?
