i put out a medium sized mouse and a pinky one for my big tegu and one for the smaller tegu.... lol my big tegu is a pain and never likes eating in the bin but she finally ate the small pinky that was meant for my little newer tegu so i left the med mouse in the bin and placed another small pinky in there and put the new red tegu in tehre and now hes trying to eat a mouse thats clearly too big for em but i cant take it from him hes determined hes ripping it apart lol i swear this red is gona be a beast.... he is chill as can be and he actually crawls into my arm from the tank already.... my black and white never does that ....before i finished typing this he devoured that mouse i dont know how he did it lol but he did now hes crawling on my bed hahahah man i love this little guy
