I'm saving 2 lives on Friday when I adopt 2 males. I called this petshop and he said he just got a shipment of feeder rats. I HATE THOSE WORDS. After controlling myself I said I'll be in on Friday to save 2 lives. I haven't had any ratties for awhile. I'm wondering if 2 males can live comfortably in a gage together. I know males get big. My cage is sort of big. 3 levels and roomy.
