It's others' business when you pursue a 'hobby' that has repeatedly proved deleterious to public health and wildlife conservation.  I don't want my grandchildren breathing in T. gondii oocytes and succumbing to horrible illnesses because they visited a playground, park or beach contaminated by your noxious, invasive, disease-ridden "community" vermin.  And their right NOT to be unnecessarily exposed to deadly zoonotic disease takes precedence over the fact you want to fondle cats without having to change a litter box.

And as a matter of fact, thanks to reading your post, I'm going to go out tonight with my suppressed air-rifle and SBB some free-roaming cats.  That's "Shoot, Bag and Bury", in case your wondering.
