I don’t know much about this rabbit diarhea stuff, so excuse me for sounding so clueless

Pudgy, poor boy. I was cleaning the pens and then I saw it: the clump!

My immiediate thought was, uh oh better check Pudge for messy bottom. Well, he has had a messy bottom before, but it was mild, the poop was matted with some fur and the vet cut the matt out for us and he was all better. But this time it was still wet! It was actually quite a mess and there was yet another clump on him. He wriggled and wriggled and wouldn’t let me hold him long enough without a fuss. I picked him up again after he had to have his lil spazz and it was gone! yay! oh joy it’s gone! I don’t care where it is, but it’s off him little did I know it was rather close to me, and when I was holding Pudge I saw that my foot was leaning back in the clump. How gross. Anyways I tried to clean his bottom but hardly any luck, there was nothing else except some wet reminance of the clumps (to much info?) later I took away his veggies and left only a few pellets in his dish. I gave him a big handful of hay, as while skimming through some threads I saw that someone had the same problem and left the bun only with hay and it worked. Well I checked his bottom again last night and it was still wet reminance and digging around in his pen, I found another clump. Oh joy. So again, no veggies (for both the bunnies) little pellets, and tons of hay. I’ve been checking on him each morning before school, just checking if he is looking good and if there are no alarming signsof illness. Anyways I’m really worried about him, would should I do? He hasn’t had any diet changes except I changed his hay to prairie timothy (same with Leila). I’ve been trying to find a good veggie to give alot of and looking around the net and BB a little bit I chose dandelion. So I give them both around 2 cups of dandelion and about 2-3 mint leaves.

Please help!
