Firstly you would have to construct a fence at least 6ft high to eliminate
the possibility of your animal escaping, it is a dangerous animal
once it is an adult. Also being a social creature it needs the interaction
of others of the same species.
You would have to ensure no cats had access to your yard, as the roo
or wallaby could contract toxoplasmosis from gracing on the grass
the cat may have soiled.
You could not have dogs near your yard as your new "pet"
could be chased by a dog running up and down your fence thus your
"pet" would end up with myopathy (a situation almost always
resulting in the death of the roo or wallaby). Or maybe running
franticly into the fence in fright and breaking its neck when a
neighbor starts the mower.
The faecies
would have to be removed on a daily basis to reduce the risk of
coccidiosis. The spraying of any cockroach, fly or ant sprays would
be out of the question.
Forget fertilising the pot plants, as most slow release fertiliser
pellets contain phosphates, this can kill a wallaby.When your "pet"
reaches sexual maturity , it would consider you one of its species,
at this stage it is capable of seriously hurting or killing an adult,
not to mention a child.
A domesticated native animal cannot be released back into the wild,
they would not know where to find food, or what to eat, where to find
shelter or how to interact with their own kind. The only answer in
that case is to humanely have the animal put down, when the family
no longer is able to handle it, or the novelty has worn off.
When we
consider the amount of cats and dogs the RSPCA has to put down every
day of the week, do you really think it would be any different if
not worse for our native wildlife if kept as pets?
