Carle is right. We should educate the public and stop abandoning these animals in the wild. It is cruel to the cats and even worse on the birds. Actually, the biggest destroyers of habitat and native species in the world are humans. Certainly did not try to offend anyone here on the forum.
Someone has a problem, and am only offering a solution to it.
If the solution is not right for you, so be it. I am not in the business of pushing my morals and religeous beliefs on others in the population. I am a tremendous animal and nature lover. Feed several bushels of ear corn each winter for the 60 or so squirrels living in the vicinity. Also place mineral blocks around property boundaries to help the deer stay healthy.
