Incidentally, all the ginger tabby-marked cats I have known have been males.  Perhaps their sisters are the tortoiseshell females. I don't say there are no ginger females, just that I haven't met one.

True grey and brownish/black tabbies, whether blotched or barred pattern, can be either male or female.  I am told that gingers are commoner in the inland - protective coloration against large raptors.

How is this possible? "Tabbys are always males for what it's worth." What do
you mean by "tabby"? The genetics of "tabby" are independent of sex, apart
from that the gene controlling whether the base colour is black or orange,
is sex linked. Thus tortoiseshell (having both the black and orange gene)
are always female, males can only have one gene. The orange parts of cats
are always "tabby", that is showing alternate patches of dark and light
tipped hairs. These are of two main types, blotched or mackerel, according
to another gene. The black parts of cats are either black or "tabby",
depending on another gene.

We have had a continuous influx of bird- killing cats from adjacent bush,
control them by using wire box possum traps available from rural stock
stores or probably online.

Best bait is Snappy Tom cat food. It seems irresistible, has never failed
over twenty years.

Big Tabbys here are very big ferals, Tabbys are always males for what it's

Once caught our local vet euthanases. them with an injection.
