Input: 
I live in an apartment building a block away from a busy street. Our building is pet friendly or at least when we moved in two years ago it was. A few nights ago around 10pm my boyfriend found a friendly black cat in the parking lot who was meowing and it actually followed him in the building. Neither of us had ever seen this cat before, we thought it might have an owner but we figured it was lost, he had matts in his fur and he was meowing loudly and acting anxious once he was in the apartment.

After about an hour and a half the cat continued to be loud any anxious so we realized we couldn't house him for the night, figuring our neighbour's would complain and we wouldn't get any sleep. We considered just putting him back out but we didn't want to feel guilty not knowing what happened to him. We found a 24 hour vet that would house him for the night before going to the local (no kill) shelter in the morning.

I had some posters printed describing the cat and letting them know to call the shelter if they are the owners or know who the owners could be. I did this although I figured it was overkill since any concerned animal parent would naturally call local shelters. I put these poster up in my building and around the neighborhood.

I was surprised to later see a response to my note by the poster I put up in the laundry room. Saying that the cat is theirs, he's an indoor/outdoor cat, they didn't see him for 1.5 days because he was taken to a shelter "without [their] knowledge" they cautioned others not to pick him up etc and then took a whole other page to talk about how he has always been very vocal and they have no way to deal with it because they don't want to "snip his vocal chords. "

I understand them being worried not seeing their cat for a couple days, but it's late at night, the cat is meowing and trying to go inside. Plus we never saw this cat in the two years that we've lived there.

I don't want to start a debate about appropriate pet care. I'm not a big fan of cats being indoor/outdoor in the city. I understand why people don't like to collar their cats. They can do what they like.

But should I have just left the cat be? We did suspect he had an owner in the area. I'm a little puzzled how these people are going to avoid situations like this in the future. And how they even manage an indoor/outdoor cat in an apartment. Is it better to just leave a loud animal at night to its own devices?

We know some of the other neighborhood cats, they aren't the only ones who have outdoor cats in the neighborhood.
