Thanks for rescuing this bunny from a dangerous situation. It’s not uncommon for people to think that a rabbit will do fine out in the wild, but domestic rabbits….are well, domesticated (have been for over hundred years already, and while they do have some strong similarities, their body shape has changed, their not as quick, they are more docile and less able to protect themselves, and it’s cruel to set a domestic rabbit free in the wild) So I am glad you stepped in to take him into your care. And though you admit you are not familiar with rabbits, it’s great that you are reaching out to educate yourself
I am glad that your bunny is eating again, but do be careful not to feed too much fruit/sweets as it can cause an overabundance of bacteria in the gut (needed to digest all that sugar from the fruit) and that can cause an imbalance that can cause the issues of what you are having now. .
In regards to the salad, I’d not give too many baby carrots as they are actually higher in sugar and give one as a treat. For the salad the romaine is good, celery is okay, but you want to cut it up in little pieces otherwise the stringy fibers in the celery can cause digestive problems. The best bunny salad is sticking with dark leafy greens. Parsley, Cilantro, Romaine, Dill, Mint, Kale (sparingly), Dandelion greens — three or more of those would make for a good balanced salad. HOWEVER, if your bunny has never had those, then you need to slowly add one type of dark leafy green to the salad each week.

The thing that does worry me though is that this lack of appetite has been going on for several days. I’m glad it seems to be improving, but one thing to know about rabbits, they will keep serious illness hidden (That’s part of their prey survival instincts) and they may seem okay one day, even though they haven’t been eating, and then they may start having less energy, but nothing seems like it’s an emergency behavior wise, UNTIL suddenly it’s too late. So, after a bunny hasn’t eating or drank for 12-24 hours, and if you haven’t seen poo either, then it can go downhill very quickly. So it would be a good idea to find a rabbit savvy vet.
