On Brush Tail Possums

At times during the night they make a lot of noise Above my bedroom on the galvanize The males engaged in a territorial fight They hiss and growl as each other they claw and bite Cats on the prowl of adult brush tail possums stay well clear Their razor sharp claws are weapons for to fear For dog, fox or cat there are far easier prey Than big brush tail possum in his cloak of grey In dark tree cavities and ceilings they hide themselves away These creatures seldom seen in light of day On the galvanize roof at night a loud racket they make And I curse them as in bed I lay awake And all through the night the males claw and snarl and bite As they engage in a territorial fight.
