I don't have a cat . . .

Some communities also have spay/neuter cost reductions for strays, not necessarily ferals. My daughter took in a stray (already had 2 in the house) and the local c-snip (low cost) program neutered him for $5 . Many animal shelters and humane societies have low cost spay,neuter clinics at certain times, sometimes a vets office will do it once or twice per year. Where there is a will, there is a way. None need to die. If all pet owners would do this, many of the strays/ferals wouldn't be around to be a problem.
