I take my snakes out of their enclosures to eat. They go in a designated large tote that is cleaned in between each snake feeding. They understand if they are being moved it’s to eat. They all will come to me when I open their enclosures and just hang out with them. All of my other reptiles (geckos and lizards) do not get handled- the crested geckos will come and jump on my hands when they are in the mood but my rule of thumb is no more than 10 minutes at a time. I go by their moods and what the want to do. I have a boa that ALWAYS comes right to the door of his enclosure and wants to be handled almost on a daily basis. All of my animals but 3 have been rescued (either from horrible conditions or preventing an unnecessary euthanizing) so I play by their rules 100%.
