Nails or claws that have grown too long easily become caught
on a variety of objects that a rabbit can come in contact
with. If wire mesh is used to enclose the rabbit the claws
can become caught in it. When a rabbit gets caught up on
something it has a tendency to panick and act frantically.
This poses a danger because they run the risk of tearing
the claw from their foot. If you notice a particular item
in your rabbits cage that they are getting their claws caught
on you may wish to remove that item.
The best way to ensure that a rabbits nails do not become
overgrown is to pay attention to them and clip as necessary.
You can also try placing a piece of sand paper in the enclosure
in the hopes that the rabbit will use it to sand their own
claws down. This is much safer than having to clip them.
If they are far too long you can attempt to cut them yourself
or have a veterinarian do it for you. If you decide to cut
them yourself take care that you do not injure the rabbit
in the process of doing so. Rabbits have nerves in their
nails close to their paws but these nerves can grow further
as the nails grow.
