all the time? snakes are optimistic feeders so if food is offered they will most likely eat it because they don't know when there next meal is coming. My PH albino female will eat once a week and only once a week(she's weird) but my albino female,my JCP and my GTP would eat every day if I gave them the chance.
Someone might be able to give you a better explanation. but thats how i see it
