Rural feral cats help keep rodent populations down, in fact with the rats over taking the cities they may be useful there yet. Raccoons and porcupines are getting to be a problem up north. Vets are plagued by the diseases they carry and transfer to household pets. However we've digressed very far from song birds. I remember a very stern lecture (perhaps a swift slap in the back of the head) from shooting my pellet gun, and missing, at a small bird. I was about 10 I think. I too love to hear the birds in the mornings, cept that bloody woodpecker in my back yard that's killing an old maple tree in the back yard. he comes back every year and goes to the same tree and drills a new hole.
