Fresh food for buns should consist primarily of leafy greens, with certain veg in much smaller quantities, and fresh fruit even less. The Bunny Info tab at the top is a gateway to the food and diet info section, which has great lists of safe bunny produce.
For my bun, he gets little bits of fresh veg and fruit if I happen to be having them, so there’s no real storage involved since I like to buy my produce in small quantities I can consume quickly and at optimal freshness (I live alone with my bun now).
But I do buy lots of leafy greens – 3-6 different kinds each week.
I try to buy whatever’s freshest. As soon as I get home, I fill the sink with cold water, wash everything really well, then remove excess water with my salad spinner. I then toss everything higgledy piggledy in my veg crisper (a big tupperware box with a lid would work well too, but my fridge is small so I stopped using a box). I just make sure that there are paper towels on the bottom of the crisper before I store my leaves, as well as one on top of the leaves) and that the little vent is closed.
I find that this keeps my greens for the week, and it makes it super easy to grab a handful and just toss it in Chewie’s salad bowl (and another in mine lol).
