That is the worst advice I have herd in a while.First off monitor need whole prey items meaning the whole body.Whole crickets,whole roaches,and whole mice.Second Savannas eat mainly insects,so why would you feed it ground beef.Have you ever owned a monitor ?They advice you have given will lead to a dead monitor with in a year.
That monitor dose look on deaths door,it is very dehydrated.You most provide a well sealed cage and give him options of temperature and humidity.give him a good dirt sand mix deep enough for him to burrow in,and give him a basking site of a least 120
