Hi and welcome!! Congrats on your little friend
I would introduce veggies very slowly
when she hits about 6 months. Her belly will learn to tolerate them then, start with one or two types of veggie and watch her for diahrrea or lameness and either switch them out or write a list of what she likes. Acceptable fruits and veggies can be found on this list:
I might also add, and stress the importance of the difference between the care of show rabbitd and pet rabbits. This website www.rabbit.org
should be your new bunny bible. Go there first for any questions you may have.
Set yourself with a rabbit savvy vet http://www.rabbit.org/vets/vets.html
and have her spayed when she reaches 6 months. Show rabbits aren't usually altered (if at all) and I guarantee you, if you don't already know, rabbits who are spayed and kept indoors can live far far longer than an un-altered rabbit.
Your bunny should see a groomer who can cut out her little tangles. Once they're cut out, brush her once/twice a day. Lionheads have a fine mane (especially behind and around their ears) which can be quite painful if pulled on during their own grooming. You will have to get her used to being brushed!! lol Pick her up and before she gets to play on the floor groom her with a gentle cat brush (I'm not 100% sure which brush is good for lionheads but I use a ZoomGroom).
You can litter train her too, but it might be easier to do when she is spayed
Any more questions, just ask!
