Hi, I have 4 sulcata's 1 is 2.5ft at present and very heavy, the other three are about a foot and a half.

I keep my sully's in a spare room, which is tropical with all the heat that they need, what i use for the substrate is loads of hay, the main diet for the sullys is weeds, grass and hay, do not feed them too much fruit, maybe once a month as a treat, lettuce is no good at all, to feed them. As the sulllys do not hibernate they need constant heat through out the year, and when weeds and grass are not available in the winter months, your daughter will find them very expensive to feed and heat when they get a lot bigger, at present my sullys, are costing me £50 a week on food alone, the electric bills almost double in the winter as i have night lights, and heaters on along with the all in one solar light, i also use a 250 watt infra red light, this is 24 hours a day.

Also your daughter will find that when they poo, it smells like an elephant house, so i can see them getting moved from her sittingroom, in the very near future, for the 2 sullys your daughter will need to provide atleast an 8ft by 6ft enclosure to keep them contained, as the sullys will eat everything in sight, they are not a tortoise, for somebody that just takes their fancy, they are a lot of work because of their size, and cause a lot of mess. If you need any advice, i am only to happy to help you, but sullys are not for first time tortoise keepers.
