Not a lot I let him do his thing all day usually when I get home from work I do some stuff around the house he just watches doesn't puff up ill stick my hand in for like five minutes them I pick him up no squirming at all let him loose on me he likes my shoulders and head normally he sits there doesn't run when I reach for him. At night he does not like to get picked up I tried already that's the only time he's pissed he'll squirm nothing more than that so I let him just rest he's super active alllll day digging making a mess in his cage. When I feed him even if I still have my hand inside he doesn't even look at me will even just brush by my hand chasing crickets.
