Your bunny will need her nails trimmed fairly often, and you have two choices when it comes to trimming nails: you can take her to the vet (though, this admittedly will get expensive,) or you can trim them yourselves.  (We very strongly recommend having a veterinarian show you how to do it the first time to avoid mistakes).

You can find specialized bunny clippers at any pet store like PetSmart. 

(Rabbit clippers are very similar to the clippers sold to trim cat's nails - so you can use the same pair for your kitties.) Or, many people report success in using the same old-fashioned nail clippers you use for trimming your own nails. 

Before you trim your bunny's nails be sure you have the clippers, some flour (just in case you hit a vein,) and a towel to wrap your bunny in, making it difficult for her to squirm and try to get away. The more you trim your bunny's nails, the more you'll discover what works best for you and your bunny.

There are several ways you can trim your rabbits nails. First, if there is someone else with you, you can have that person securely hold your bunny wrapped in a towel (to prevent scratching) while you trim the nails. You can also sit the bunny on the floor, gripping her between your legs. This makes it easy to trim the nails on the front paws, but you'll need to be creative to trim her back feet nails. 

When trimming the nails, look for the line that indicates a vein. If your bunny has dark nails, you may not be able to see it. If you can see it, do not trim into the vein or beyond. If you cannot see the vein, simply trim a VERY little bit. This way, you won't accidentally hit a vein; however, you might have to trim the nails more often.
