I want to introduce Patches and Rio together once I get my 2x6 cage. I know you guys said to give Rio alfalfa hay because it'll help him grow, but not to give Patches alfalfa because he's fat, so how do you seperate the food? Are males hard to introduce? How do you do it? What happens if they fight? I'm literally scared to death to put them together. Patches is about 7 times larger than Rio. Should I wait until Rio is older so he stands a chance?
