Feline apologists aside notwithstanding, if you (as we do)
acquire your moggies by rescuing them from the (R)SPCA or
elsewhere, chances are they will have lived 'rough' at some
point, and thus learned to hunt. The 'right thinkers' will
tell us that this is the 'proper' way to acquire pets, versus
at a pet store or breeder.

Two of the four cats in our life came from the SPCA, and the
other two were feral-born at a barn and requested us to bring
them home at about three months of age.

All are gentle, grateful, affectionate (sometimes overly so),
and very grateful indoor companion cats. They never, ever,
are deliberately allowed to go outdoors, and at least two
of them are now afraid of 'the world.' One of them enjoys
going out for a swim in the pool on a very warm summer day
(polydactyl (full thumbs) Maine Coon Cat tiger).

All are unrepentant, unapologetic, recreational murderers and
mutilators of any creature from bugs to mice that might invade
their space, which they then present to their benefactors.

The remaining barn cats are (mostly, when we can catch them)
spayed or neutered, and then fed. They continue to present us
with their 'catches.' We rarely see feathers, but disemboweled
mice and moles occur at least weekly.

The mouse police never sleeps.
