Hi, welcome to the forum congratulations on the new rabbit! : )

If you mean like a bunch of grapes, then that is the cecatropes, also called cecal droppings. Are they really shiny too? These are the specially fermented dropping that rabbits eat to get vital nutrition. It’s technically not poop or waste product. It’s a super nutrition product.    We don’t normally see them but it isn’t unusal for a young rabbit to produce an excess of them.

What is his diet like?

Sometimes, if there are too many extra cecals around or they are mushy and unformed, then the diet may need to be adjusted. To much sugary or starchy treats can cause an imbalance in the gut.

I’ve never seen any cecotropes in person myself, but I’m pretty certain I’ve smelled them once or twice, when I was a little too close to one of my buns when they were eating them. Is Benji eating any of those cecotropes/cecals?

I see you’re already getting used to picking up the “regular” pellets – I personally like to call them “bunny berries”, though I forget where I picked up the locution from – and tossing them back into the appropriate place. That’s a basic rabbit-person skill. And you’re quite right, those poops are pretty much all waste hay. They don’t smell and they’re normally very hard and dry, even crumbly, in texture, and range from golden-brown to medium-brown in color. On a yuckiness scale of 1 to 10, where 10 is maximum (I’d assign dog poop to that), regular healthy bunny poop is pretty much a 1 (of course you’ll wash your hands afterwards, poop is still poop!)
