"Experts aren’t exactly sure if reptiles have the ability to bond with humans or not. Dr. Denish believes reptiles show emotion—but in a limited form. 'Most of their life is about basic necessities like drinking, eating, breeding, and surviving,' he says.
Snakes have been known to show excitement and curiosity, too. 'At the zoo,' says Dr. Denish, “we see snakes that are interested in new forms of enrichment like bedding, housing, or a new scent.'
Actual love for a human, though? That, says Dr. Denish, is difficult to prove.
But as long as you feel a connection with your pet, that’s all that matters. The more time you spend nurturing your pet, the better it’ll be for both of you. You’ll be more comfortable around one another, leading to a greater chance that a “bond” will form—whatever that bond may be."
