This sort of crosses into the 'Weird RL' but it was kind of charming.
I have always sort of 'adopted' cats unwittingly. Nearly everywhere I've lived, I've had the area strays realize I am the Local Friendly Cat Lady and just sort of wander on by from time to time. In NKY, my house faced the building next to mine rather than the alley directly, so my yard (slab) was fenced and a safe spot to hang out and get away from dogs, kids, etc. I ended up ultimately, there, setting up a sheet of metal as a shelter from rain and snow and would put out food for the strays.
The best was the time a momma cat brought her babies to introduce them to me. 
ANYHOW.
Last night, as I'm dozing off, I hear this loud MEOW from the direction of my living room. I start awake (because neither of my cats meow unless something's wrong), but both my kitties are by my legs and both are staring that way, too. Confused, I get up and head for the living room with them following.
I look out onto the patio and there's this round faced tabby, pawing at a trash bag I'd put out earlier. You see, when I clean, I'm usually wiped by the end of it (thanks, fibro), so I'll set the bag on the patio and take it out the following morning once I've rested. Every so often, I've found little holes torn through it. Well, that bag had no food trash in it and this little tabby was apparently quite cross with me for that. I guess he had decided I'd been putting food out for him.
As soon as he saw me at the door, he looked up and began up his complaints: meow meow meow meow!
Oh, well then!
I keep two bowls of food for my cats in separate rooms and they sometimes have fits of ignoring the smaller one and eventually, it gets stale and I have to throw it out (the thing that may have begun this whole situation!). They'd been doing just that this week. So I went, grabbed the bowl, and set it outside the door. Mr. Roundface promptly went up and began chowing down while my kitties watched from inside.
When he was done, he looked up, walked around the patio slab, meow meow meow! and wandered off.
I guess I'm just glad the food is being eaten rather than going to waste because my two are picky af.
