I noticed that I haven't been on the receiving end of this too often, mostly the causing end. My favourite is "do I have to re-upload my jpegs when they fade over time?" I wish we lived in that world. I think.
But cat treats. They don't tell you how much you're meant to give the cats. I wasn't sure if it was "one" or "some" or "many" and my assumption was somewhere in the some-to-many range. The revised answer I came up with—after conducting the requisite science (i.e. cleaning up cat vomit)—is "one."See you, space cowboy.
