Hello everyone! First time poster here! Feel free to move this topic to somewhere more appropriate since I’m not very forum savy! 

We’re adopting a rabbit from a friend who hasn’t been able to take care of her for a few months now. She’s been left with friends that have just been ‘keeping her alive’ with feeding, basic cage cleaning, and water. (I was rather heart broken to hear about it, and we’re very happy to be adopting her and getting her the proper life she deserves)

As far as we know she’s been fed pellets and only pellets for at least the past few months. I have no idea what her diet was before that or even what brand of pellets they’ve been giving her. We’ve taken her out to give her some lovin’ and attention a few times and she’s wee’d in the play pen. Its been a milky light brown color (which, from what I read, can be indicative of poor nutrition from a pellet only diet). Obviously we’ll be taking her to the vet to get checked out and any appropriate vaccinations for our area, but that’s all dependent on when a vet that has bunny experience has an opening once we’ve moved (which could be anywhere from three days to a week). 

My concerns lie with what we’ll feed her straight away. I want to put a hay/grass source into her pen once we take over, but I’m just not sure if it would be a bad shock to her system to start her on the right diet without a transition. (I know bunnies have delicate GI tracts I just don’t want her to suddenly see these wonderful foods before her, pig out, and put her system into an even worse state.)

Anyone have any advice on easing a bunny back into good food?
