Consistent clear pee is unusual for a rabbit and is indicative of a lot of water consumption. It could be in reaction to the grass which made him more thirsty than usual due to making him pee. There is always a chance of harmful chemicals and just gross stuff on grass that can affect a rabbit. If it still persists after you go back to normal veggies, I would go to the vet and see if he’s having mouth issues that he’s trying to lubricate with water.

Do you feed him parsley? Parsley makes some rabbits pee a ton, so they drink a ton to compensate.

When my bun was almost 4 months he drank 3-4 bowls of water a day! Giving him veggies really helped so make sure to give them to him very day

I’m a new bunny owner and I’m not quite sure about the clear pee but all I know is that it’s pretty unusual and if it keeps happening, really make sure you take him to the vet ASAP! Like Wick said, see if he’s still doing these things after you give him veggies again. Sometimes when rabbit eat just hay, it makes them very thirsty. I’ve experienced this a lot with Toby, but again, veggies are a life saver for this issue.

I would also continue to monitor his water consumption. An increase in consumption as well as in urine output could coincide with kidney failure, diabetes, UTI, and even E Cuniculi. Not saying any of this to scare you but if you suddenly notice a big increase I would closely monitor and if he doesn’t seem to go back down to his normal amount and/or is peeing a lot more it wouldn’t hurt to bring him into the vet and have them check everything out! More than likely none of the above is the reason, but it’s  important to always monitor those things closely <g class="gr_ gr_2746 gr-alert gr_gramm gr_inline_cards gr_run_anim Grammar only-ins replaceWithoutSep" id="2746" data-gr-id="2746">because</g> rabbits hardly every show symptoms of illness until its too late. <br>

Thanks Tilly!
I did ask someone why my bun was drinking more water when he was younger, and they said it was because I hadn’t introduced veggies to him yet. After introducing veggies, he stopped drinking all the amounts of water he used to drink. But since you said you gave him veggies, it’s a bit odd that he’s still drinking all of this water. I’m crossing my fingers that your bun doesn’t have any sort of kidney issue. Oh wait a second. You live in Australia! This isn’t an experienced answer, but it definitely is a logical answer. Maybe your rabbit is drinking all of this water because of the heat! Even though rabbits have veggies, when the weather is very hot, they will still drink a ton of water. I live in the US, and it’s super cold here right now. But Australia! That’s HOT! Is he an indoor or outdoor bun? Either way, Australia is very hot, so that’s the only thing I can think of. About the shedding fur, that doesn’t have anything to do with it. Toby is currently shedding, and he’s not drinking a lot of water. But again, I hope your bun is healthy, but if you want, you can take him to the vet anyway. It’s always good for a rabbit to see their vet, even if they’re not sick. Hope this helps
