It seems to me that it depends on the relationship with their owners...Also wether wc or cb...
I had 3 Chaco tortoises since they were babies and they came over when we called them... But you had to keep on calling them for a long time. I heard tortoises don't hear very well except low tones (?). They ate off my hand and put one of their "hands" on mine. They were shy with strangers though.
Toto my greek tortoise also likes to eat out of our hands. He likes to cuddle on our laps and puts his nose next to our faces. He likes to be petted under the chin. Perhaps because he is CB he is used to be handled by people? He is not shy with strangers. He also goes shopping with us in a little pull up plastic cart.
He is good friends with the cat. They sleep together cuddled up in a box lid full of confetti. When the tortoise is in his outdoor enclosure the cat follows him with the eyes. He sits next to Toto and scares the birds and anything else away -not that they would harm Toto but the cat is very protective of his little shelled friend...
For Halloween they are both sporting matching witch hats... just for a brief photo shoot of course...
Have a good weekend...
