I agree. Feral cats, protected by animal-loving kooks, slaughter tens of millions of song birds every year.
They should be trapped, and eliminated.

My two fuszzies get 3 to 4 rats per week. The occasional song bird upsets me, but keeping the rodent population at bay pretty much makes it worth it. Living on 33 acres invites a lot of unwanted visitors.
trapping then releasing them has a better positive pressure on other species. this way territories are inhabited by non breeders
