Well what we interpret as "liking" may not necessarily be them liking it. I've looked into scientific studies of this stuff and keep coming up empty handed unfortunately. I'd LOVE to see proof that they are capable of those emotions because I find it fascinating, and I like to think my snakes enjoy my company and enjoy being held and feel more than just "trust" towards me, but I haven't seen any of the scientific proof behind it, which is why at this point I said "I think" they just tolerate it, or trust us, or know our scent. Whatever it may be, I wish the studies were readily available like the stuff on cats and dogs.
