Hiya,
Luckily when I leave home I'm visiting my parents, so I have a full set up there for Guac an take him with me. However for some of my job interviews this year I had to leave for a couple days pretty regularly, and I also met my SO's family this yea which meant almost a week away from my baby...
For short trips, I do lights on a timer, fresh bowl of water, a small amount (next feeding's worth) of fresh greens and dry pellet foods. I never feed pellets otherwise, but I keep them around for emergencies like when my car got totaled (tree fell on it... and me...
) a year ago and I couldn't buy food for Guac as easily. He'll eat them if he's hungry, albeit begrudgingly, and I figure it's better then nothing when I'm not around to feed him.
If it's something you can do though, a housemate, neighbor, or family member coming in to be a green delivery is great. I even put together little "shake me" packs of dubia roaches + a little carrot and calcium powder for the relatives that aren't squeamish about such things. Works out great.
I have heard of some places boarding beardies, but I am a bit shifty on the idea... IDK why. Probably a great options really.
If you have a trustworthy interested friend or neighbor, that's almost always the route I would go with. When I was in college, for instance, I did a little pet/house sitting. I'd water your plants and take care of any "box/pocket pets" (rodents and reptiles essentially), as well as cats and dogs on a case-by-case bias. Since I was one person people could hold responsible, as well as being fairly responsible and having all sorts of pictures to show of my happy-healthy pets, I had a P. good little business going for a little bit. Obviously has to be someone you trust though.
Real talk though I am a biology major who works with a bunch of hard-science nerd animal lovers, so the one time no one else was available and I really needed a sitter for Guac and the rest of my scale-babies I just paid a coworker to stop buy and feed/clean everyone.
Hope this helps? Big trip in the future?
Anyways, best!
