Bunny suddenly lethargic

[brendap]

So I first got my rabbit about a week ago and from the very beginning she’s been very active, especially once the clock hits 7:30 pm. Since I had her I was feeding her a diet of timothy hay and pellets, however, I wasn’t sure if she was too young to start introducing veg (she’s 3 months) but every forum I read said it was okay. So yesterday I went to whole foods and bought her a box of baby spring mix and gave her a bowlful which she loved and devoured quickly, later that night I gave her another bowl and by the time I woke up she had finished it so this morning I gave her veg and pellets, she ate all the veg but left some pellets, now she’s usually a very active bunny but today she’s been sleeping inside her igloo for most of the day, she came out to eat and pooped (a LOT) but then she’ll go back in her igloo and lay there. Her poop seems normal (dark, round, and hard) but she just doesn’t run around like usual so i’m pretty worried it may be the veg since it’s the only thing that has changed since she started being lethargic. Any advice on what I should do?

Welcome to the forum!
You should go a couple of days without the baby veg thing. Have you checked what exactly is in it? Not all of what we eat are good for your bun, like spinach or mustard greens, bear in mind, see if she has any other signs of worry. Give her plenty of hay and water, and just for safety's sake, you can call around vets to see what they say. Here's a good link on what is safe.

Greens should be introduced very slowly and only one type at a time over several days until you are sure your bunny can handle that type of green. If I were you I definitely would not feed any more greens right now. Hopefully the more experienced members will be along shortly to help you but as Catlyn said, a call to the vet is never a bad idea.

I also think that she's got too much vegetables, also she's only 3 months old and it is best to keep her on hay+dry food until 4-6 months, then you can start giving vegetables but as said above one at a time and not much, one handful a day would be fine, I think you just got a bit over excited that she liked her new vegs and gave her too much. I would keep her on hay for a couple days and also if you got gas drops or I give my rabbits dried herbs when they are unwell, chamomile, mint, that would help her stomach to digest it. I had similar situation with my first rabbit, he was 9 week old and was so happy when got mixed leaves and I was so happy he's so happy so I gave him more, next day he was very passive and his stomach was a bit hard so I was very scared too

New foods(aside from grass hay) should always be gradually introduced into a rabbits diet, starting with one at a time and in very small amounts. This gives the rabbits digestive flora time to adapt to the food changes. After a few days of the small introduction amount, if there are no signs of upset then it can be gradually increased in amount.

For now I would stop introduction of veg for several days until everything is back to normal, then do a more gradual introduction of one plain green at a time. I would also encourage more hay eating(ensuring more hay is actually being consumed) by slightly reducing pellet amounts. This helps get the gut contents moving through better and helps restore proper gut balance.
