I did check the temps and humidity. He has eaten the last 3 times but refused the first 3 times. The first time he ate i had to leave the rat pup overnight and the second time he instanly went after a mouse hopper. The 3rd time he ignored the rat pup for hours until i made it "dance" around. I dont know if he is a picky eater or if he needs movement to get him excited. Could that be it?
