Housing your Rabbit properly

Cage Location:

The first thing you will need to do is determine the location of the cage for your rabbit.
This will determine the type of cage that you will need for the rabbit.
A rabbit can live either indoors or outdoors.

For an outdoor cage you will need to make sure the location meets the following requirements:

It is well protected from the weather. No wind, direct sunlight, moisture,
etc. can reach the inside of the cage?
It is protected from extreme temperatures?
A rabbit should have extra protection, such as straw or hay for bedding,
when temperatures get near or below zero. If the cold is extreme,
other means of heating should be used. However a rabbit can handle cold
temperatures much better than heat. When temperatures rise above 80 degrees,
a cooling method should be used.
A good suggestion is to use frozen bottles of water or ice packs in the cage
for the rabbit to lay against
a misting system outside of the cage, evaporative cooler, air conditioner, or fan.
It is protected from other animals?
Dogs, cats, and wild animals can pose a severe threat to the rabbit.

Your rabbits housing should be well ventilated and provide adequate
daylight (however not direct sunlight) during the day.

For an indoor cage
you will need to make sure the location meets the following requirements:

It is protected from other household pets that may pose a threat to the rabbit?
It is located in an area that has adequate light?
Are electrical cords, clothing, plants, etc out of the rabbits reach?
Rabbit can and will reach through the wire of the cage to get at something interesting.
. It is not too hot or too cold in the location that the rabbit will be housed?

Cage Sizes:

Cage sizes will depend on the size of the rabbit.
A small breed rabbit can be easily housed in a small 18 x 18 cage.
Where as a larger breed rabbit should be housed in a minimum
of a 30 x 24 cage.
Small breed Does with litters should be housed in a cage at least 24 x 18
Larger breed Does with litters require more space of approx 36 x 30
