Stop feeding the cats!
Pretty much the title. I was walking to my apartment with my mom this evening when we were accosted by a boomer who I've never seen in the complex before. For context, for the past 4 1/2 years, we've taken care of cats that love around our complex, including feeding, watering and making sure they get neutered/spayed to prevent baby cats. The apartment complex knows we do this, and only requests we don't feed the cats on property, which we don't. We feed them across the street by a business who also knows what we do.
The boomer couldn't even be bother to say hello first, just instantly jumped in with "Stop feeding the cats!" We told him it's fine with everyone except him and he retorts "Well they pee by my front door and are annoying to see." Dude didn't care that we feed them in the opposite direction of his apartment and held firm. "Why do you do it anyway?" Like, because I'm not a piece of garbage and can care about animals like a normal person.
I got tired of trying to get through to his lead addled brain and ended up walking away. In almost 5 years he's the first to complain so I'm just gonna keep doing what I do.
