Sometimes there's a cat in the inner yard of my apartment building. It even rolls on it's back to let me rub her belly. This made my entire shitty week two weeks ago.
After doing a lot of spring cleaning and clearing some space where a bunch of random stuff was piled up, I moved an unused kitty bed to that area. One of the kitties is in it for the first time this morning. That's almost as good as meeting a new kitty, cause it's a familiar kitty in a new space. Bonus: the new shelves I assembled over the weekend for vinyl records have one space open for the kitties (on the second row) and the other kitty was in there for the first time this morning, too.
And sometimes the cats you meet even let you pet them. :3
