I do this too, but it's important to make sure you're either fully adopting them to keep them inside and care for medical issues, or at least make sure they get neutered/spayed before they're let out again if they can't live indoors. Stray cats are terrible for the local ecology- just feeding them without taking those steps is definitely harmful. In my town you can call animal control for strays and they'll clip the ears so you can see that they can't reproduce and are safe to leave out.

I'd also be hesitant to give people the idea that racoons are safe to interact with, even stray cats can be dangerous, but racoons can do much more damage. I feel like the ideal situation is they capture him and find an animal sanctuary away from the public. Wild animals with genetic issues don't usually live a great life

They can take my bird feeders from my cold dead hands.

You do you, but I'd ask in earnest people please don't. Cats are invasive to the US and wreak havoc on local wildlife populations. Where I live, so many people feed the ferals that they've become an overpopulated menace.

When I lived in Chicago I'd see rats and cats eating cat food left out alongside each other. I'm not against helping wild animals as long as it doesn't come with a rat infestation issue.
