I've had a random cat appear on my apartment patio three of the last six days this week.
The cat seems to be in good condition so I think someone takes care of it but it doesn't have a collar. I have not given it anything except petted it because I don't want to be adopted by a cat.
Its cute but it needs to go back where it came from.
Its not patient with having its picture taken but I did get a few photos:
