I used to have a Savana Monitor that I bought from a pet shop when it was about six inches long, nose to end of tail. By the time I had to find it a new home he had reached about four feet long.
He started on crickets. Them moved up to "pinkies." Then to adult mice. Then to immature rats. By the time he was four feet long, I was feeding him adult rats, and the scene in your vid is very familiar to me.
PS I knew a guy who had converted several rooms of his home to correctly accommodate his various pet reptiles, and he was happy to take him off my hands when he outgrew the huge tank I was keeping him in, which for him was getting way too small.
