"have you seen my cat?"
that's twice, this week. and, here's the hard truth for windsorites: your cat ran away to join the colony, and you'll have to deal with it. the feral cats here have a really strong invisible network of scent signals that will lure your cat away immediately, if you let sight of it for even one second, outside. i wouldn't even be surprised to hear about cats darting out when doors are left open a crack, after waiting all day to follow the smell, as it walked by outside.
i've been arguing that the city needs a serious straight out feline cull. i know what they say about how trap, neuter & return is a preferable option, but that presumes a certain level of manageability. we may, unfortunately, be at the point where we require an all out slaughter of feral cats, because their existing numbers are already too much of a problem for a t-n-r to cut down on.
but, the colony will in some way affect your cat, even if it's isolated enough from the aromas that it only gets the odd sniff of it. the ones that it drags out, zombie like, will be converted to the cause of the colony upon arrival. and, this is simply hormonal - no amount of pleading will change your cat's minds. once assimilated, they are gone - never to return to snuggling, or to the far more subversive kneading, at that. their minds are washed of their existence as slaves to humans, however absurd that formulation is when related to cats, and given a new life of meaning to protect, defend and expand the colony. do not waste your time - they are gone.
as it's purely chemical, and we're both basically the same kind of mammal, of course this is possible in humans, if you can find the right magic password, the right chemical bonds. you can get an idea of how we're sometimes driven purely by hormones when you look at the fight or flight response; we literally don't think in these situations, we just succumb to this hormone that forces us to react. this is a ways from actual chemical mind control. and, the instincts available to program are likely to be biological responses that might not be useful and might even be dangerous - lust, for example. but, i think the chemistry likely exists to turn a human's brain right off in order to accomplish a biological urge, and it would probably be experienced by the conscious host as a blackout in memory. one could no doubt find detailed examples that fit this description.
if you lose your cat around here, though? it's gone. to the colony.
