How long will you be gone?

If it's not for very long, then I think the snakes will be fine on their own.

Just remember to spot clean & scrub dishes. Since snakes can go a while without eating, I'm sure your snakes will be fine if you're not going to be gone for long.

To be honest, I don't trust anyone with caring after my snakes. So if I know I'll be gone a while I won't go to where ever I was going to because I know I'm the one responsible for caring after them and they are 100% dependant on me.
