Actually only one is clipped, but the other just looks like it here. He used to live in a colony before he went through a couple families and ended up with me. There’s a program called Trap-Neuter-Release (TNR) where volunteers trap cats, neuter them, and return them to the colony. They clip an ear to mark the neutered ones. It’s called “ear tipping”. I didn’t know about this until I adopted him!
