Comming from a Monitor owner, Sav's really dont make great pets some will tame down with handling other will never tame down its a gamble. As for care needs they arent all that hard to care for over a Bearded just need a bigger enclosure as they get older 8'x3' would be about the min for a adult thats being fed a proper diet. There feeding needs are different than most monitors as they will stay on insects their entire life even in captivity they should be fed crickets, roachs and other insects, with rodents being more of a treat than a staple. If you have mosre spesific questions I can try and answer them for you Savs are one of my favorites.
