You can actually set up a free choice feeder for them that will provide food for a week or two. You can also set up a watering system with a little lick fitting that will provide them with water when you are not there. I travel a lot for work and set mine up that way so no one has to take care of them while I’m gone. My kids still go check on them but it isn’t necessary. I think it is more for their own enjoyment.
