I actually love seeing an ear-tipped stray cat. It gives me a warm feeling that someone has cared for them enough to neuter them, which means they've also been fed. If we didn't ear-tip them, it'd be a real problem. I have a female in my colony whom I sent off on TNR only to be told the next morning (after she spent the night at the vet's scared to death) that she was already neutered (she had a tiny tip on the RIGHT ear; whoever did that stupid thing must've been crazy). Since that awful night, she's been getting so much compensation in way of yummies and jowl-scratching that I'm starting to feel less guilty.
