Obvious there are people on this list who find it unacceptable.
But here are some objective questions which its interesting
to consider with my opinion in brackets.

Does the presence of domestic cats in suburbs:

a) decrease the density of some bird species?  [very likely]

b) increase the density of some bird species?  [very likely]

c) increase/decrease the density or biomass of birds in total?
[who knows]

d) increase/decrease the number of bird species present?
[I'd guess increase more likely, but hard to guess]

e) change the bird species present to more/less like the pre-european
fauna?  [who knows]

[ but of course introducing new felid genes to Australia is a very
bad idea ]
