This will facilitate taming. A suitable box should be provided. If cardboard boxes are used, make sure the box is strong enough to support the monitor's weight, as it will sit on the box. Monitors are extremely intelligent. Further, anything inside the cage, including the doors, should be strong enough to resist pushing, scratching, and tail lashing.
Savannahs are indescriminant, and voracious eaters.
They will eat anything they think is edible. As they get older, the size of the rodent can be increased. Aquatic food will be eaten, but not often, thus, it is rather pointless to provide fish. As a general rule, Savannah monitors make wonderful pets for anyone with the time to invest in properly caring for it. Their tameness and human toleration makes them extremely rewarding pets.
