I've been reading a bit on the classification of cats (feral) in QLD - they are
ranked the same as rabbits, yet people are free to own and do what they will
with them (eg, not mandatory for desexing/registering). Owing a rabbit comes
with a $40k fine in QLD. The difference - rabbits, as a class 1 pest, impact
the economy by ruining pastoral lands, cats **only** eat a phenomenal amount of
wildlife and spread toxo - neither of which (short term) cause enough stir for
action.
Frustrating!
