If I may dare to once more venture into the heady Realms of the Masters of Knowledge and Wisdom.....
I believe that indeed, some reptiles know their owners, probably by smell rather than anything else.
When my iguana Clover sees me come out on the patio in the morning, he immediately begins to raise up his head and close his eyes in anticipation of my stroking him, before I even go near the cage. He will not do that with anyone else. Iggy is learning not to move away from me, but he is very nervous of anyone else.
Neither of my iguanas will tolerate the sight of me in hair curlers, though.

Makes both of them really upset, so I never do it again.
