Dont know if this is beating a dead horse, but I put 1.1 ASFs and 1.1 rats together right as they were weaned within days of each other. They have been growing together for 2.5 months now. They stick to opposing sides as far as sleeping, but they play, sleep, etc together. I thought it would be a cool rodent social experiment, to see what would happen. So far so good. I dont think breeding them is a possibility though, rats are way too big.
