Another cat myth: "Cats are meant to roam free."

I've heard so many cat owners say "Cats are meant to roam free." Five thousand years ago cat's ancestors ran free but in the meantime...
As the domestic cat developed it underwent a number of morphological adaptations which today marks the ancestral african wildcat and the modern domestic as two distinct species. A less strictly carnivorous diet, has led to a modified digestive system - through generally being cared for and not having to survive by its own wits, its behaviour has become less aggressive and body and brain size have been reduced.
It is morally and ethically wrong to allow these animals to encroach into our ecology it is unsuited to survive in without subsidization. Doing so can be depremental to property owners in the area, to other animals it encounters, and to the cat.
