TIFU by releasing a cat from a trap

There are a few missing cat posters in our neighborhood. One is on the stop sign on the edge of the cult de sac. The cat is described as a flighty cat who runs away from people. My wife saw the cat on the poster in our yard but of course it ran away.

My own cat went missing about a year ago, so I own a couple of catch and release traps.(Yes she was found) I set one out in our yard with a can of cat food on a paper plate. This morning a grey fluffy cat was inside. I brought the cat inside and went to check the poster for the phone number. When I looked at the picture on the poster I realized this wasn't the same cat. They looked similar but the cat on the poster was an almost completely grey short hair tabby with a few white stripes. The cat I caught was a long hair domestic completely grey cat.

Now I'm not a fan of people having indoor/outdoor cats, especially since we live country adjacent with coyotes, but I also know the cats in our neighborhood are good at staying in the neighborhood. Not my place to judge you how you raise your cat. Thinking this was just one of our neighborhood cats, I released the cat and let it go.

As I was driving to work I glanced over at one of the missing cat posters and realized that poster was of a different cat. A grey fluffy cat. There are two grey cats missing in our neighborhood and I have never paid enough attention to the signs to realize they aren't the same cats.

So I realised someones missing cat after I caught it when I was trying to catch a missing cat to return it.

TLDR. I didn't pay enough attention to the missing cat posters to realize their are two different identical cats. I let a cat I caught go because it wasn't the same cat on the poster near my house.
