Something being “awful” is a matter of opinion...He also killed coons as they carry rabies and also kill birds...He was born in 1901, grew up on a farm and his family raised their own food..I would dare say, he had more smarts than you could ever aspire to...God didn’t save the pigs and cows they had to slaughter for food and I don’t think feral cats are a priority. They also carry rabies...Man is also a predator and part of the chain of life...and sometimes animals are just vermin, like feral cats and coons, possum, ground hogs etc etc etc...Mother nature is not a sweet little old lady...Feral cats also starve, get taken by hawks or preyed on by coons...So don’t let your bleeding heart drip on my. Personally, I love cats, not feral animals of any type...
Alot of ferals—I know this first hand—can become quite tame-—but most cats are strays..who once had a home ....but got lost or were dropped off by irresponsible people...and I am sure many of them your dad shot were just trying to find their way home....or looking for a kind hearted person to give them some food. To judge an animal simply because it’s walking around on your property is unforgiving.
