If you have the room and finances
available,this type of outdoor cage is highly suitable
for your very active and agile chipmunk.
Whilst it will work best the bigger it is in length and
width, height is not a big issue as in the wild chipmunks
will rarely venture above two metres. However consider
your own height as it will get very uncomfortable if you
are always ducking.
If on the other hand you want an indoor cage there are a
few things to note. firstly, the cage should be at least
90cm high by 60cm deep by 45cm wide. You should be able
to find this size cage even if it is not specifically
designed for chipmunks, you can adapt a chinchilla cage
for example.
