He eats at least 3 piles his size of hay on top of that, if not more. I don’t have the problem of hay all over because he is a little vacuum, if I drop some he just runs over and sucks it up. And just to be clear my greens aren’t just lettuce they include grasses, herbs and other forage (wild plants tend to be much more fibrous, but agree with what you are saying @DanaNM ). I am trying to mimic a natural diet as much as possible, and amount varies as I let him set his own amounts, today for example he gulped down breakfast which was about a cup and a half in a matter of seconds, but then other than pick out a couple dandelion leaves has ignored the his lunch, given it’s 7PM now and he is busy playing (he’s exploring my room which has been off limits for a week, so it’s very exciting, so he’s doing laps and climbing all the things), he may end up eating his lunch for dinner and then only having a little over two cups, yesterday he decided the world didn’t have enough food so was on the higher end of his range. It really ebbs and flows, he had one month he was not into greens other than maybe a handful or so, I was worried for a bit at first, but his hay eating never slacked. But yes he can be a voracious little eater, I know his diet is maybe not a good example for every bun or owner! Dorian’s weight is spot on and he’s a young healthy active bun, but of course will adjust if it ever causes weight gain or on vet advice.
Heh, I just realize this might be the bun version of intuitive eating! Which I find also works great for some people, but not so great for others. Also he is done rampaging and chowing hay over finishing the greens, so I feel he is good at making healthy choices for himself 😀
