Grooming
Baths
Rabbits do a great job grooming themselves and rarely (if ever) need an actual bath.
They are like cats and spend a good portion of their day cleaning themselves (and their bunny friend if they have one).
Most rabbits hate water, and so baths are not only unnecessary for rabbits, they can also be very traumatic.
In some cases, you may need to clean your rabbits behind or paws, but if at all possible use baby wipes or a wet facecloth.
Brushing
Some rabbits will only need brushed when they shed but other rabbits, such as an angora, you will have to spend time each day grooming them.
Use your hands to take out any loose tufts, then use a brush to get the extra loose fur.
If your bunny ingests too much fur it is hard for them to digest and can cause belly issues.
Nail Clipping
In the wild, rabbits dig often which keeps their nails filed down.
Some domestic rabbits will dig at their cage which will help keep nails at a good length but you should keep an eye on them.
Some rabbits, especially older rabbits, don't dig as often and so it is important to keep them clipped.
Lay rabbit on their back between your legs. If your rabbit seems nervous, place a towel over their eyes to help calm them, just be careful of the quick. You may want to ask someone to help you.
Litter Training
Provide a small cat litter box with low sides and no top. You can also purchase small animal litter boxes at most pet stores like Pet Value.
For litter, use recycled paper litter such as Yesterday's News. Stay away from clay-based or clumping litter, as it is very bad for rabbit's respiratory.
Most rabbits will stick to one area of their cage to use the bathroom, if so, place the litter box in that spot. Add a few droppings to the box to help attract them to using it.
Rabbits like to eat hay and poop at the same time so place some hay next to the litter box as another way to encourage them.
