No, I’d board him. Even if it’s for a longer period than what you would leave him. Too much could go wrong in 24 hours.
-Water bowl being tipped over/back up bottle jamming
-Running out of hay
-Soiling in hay
-Getting injured etc

I think it’s fine. I’ve left Wick alone for long periods of time. He’ll just be especially hungry when you return, but just feed him veggies and pellets when you get back.

As for water, you can do two bowls in different areas of the room, heightening the chance that at least one will remain unsoiled.’

It’s only a day, so he won’t starve if he has hay but doesn’t have his typically scheduled veggies and pellets!

EDIT upon reading STG’s reply: I should’ve noted above that Wick is not a destructive rabbit (does not chew or bite on any objects) and he’s been free-roam in my space for a very long time, so there’s no where he hasn’t gone that may be injurious to him.

If I am reading that right, youll be gone less than 24 hours? Saturday morning (for sake, Ill use 8am) to Sunday at 12am means youll be gone for 16 hours. I would leave my bunnies alone for 16 hours. I would make sure they each have their water bowls filled, have an overflow of a hay, and a clean litter box. My bonded pair have a room to themselves thats completely bunny proofed, and my single, Badger, has a large pen thats locked and capped with no risk of escaping. Because I know they would be safe, I would leave them home alone for the 16 hours.

Unless you meant you will be gone over 24 hours, from Saturday morning (using 8am example again) to Monday at midnight, meaning you would be gone for 40 hours. I would never leave my rabbits alone for 40 hours. If I couldnt find a house sitter for them/couldnt board them, I wouldnt go on the trip. There is no possible way to ensure their safety if you leave them alone for that long.

Yeah, I’m reading that as ~16 hours as well. In my opinion, that would be fine. Just make sure you have everything prepared for your bunny ahead of time.

Am I just a worrier? I panic if I have to be away for just the day! 

I customarily have to leave my rabbits by themselves for 12-13 hours per day Monday through Friday while I’m at work. They’re secured in their condo, with ample hay and water (always refreshed literally first thing in the morning), plus things to chew (willow sticks, cardboard pieces, etc.), and being a closely bonded pair have each other’s company to enjoy, plus which it’s the daytime so they spend the bulk of the period lounging or sleeping anyway. They’ve never run into any problems yet aside from knocking around their hidey boxes on the condo’s upper deck.

And I still worry.

Personally, I would rather have someone check on them in a 24 hour period, but if that’s not possible, I think its far less stressful for him to stay at home by himself for 24 hours than to be boarded or go to your parents for two weeks.

What about a pet sitting website? I’ve used someone before, just to pop in and refresh hay and water. You can tell them not to touch him etc, and to let you know if he hasn’t eaten his veg or pellets.

If you did leave him, you could try hiding his pellets etc so he doesn’t eat everything in one go.

Yep I’d leave my fluffykins for 24 hours if he was his normal healthy self. Great idea of scattering the pellets around. Plenty of extra hay, a few extra toys, and a couple of water bottles. Most id worry about is him getting bored!

You can set-up a mounted camera if you get paranoid.

I personally would leave him alone since you have him secured and his areas bunny proofed Just make sure he has enough food and that if you reach an emergency, that someone will be able to go are for him.
