You know that cat look - when they suddenly pause and glare at something, pupils slightly dilated, curious with a look of very mild confusion on their face? Yeah, that look. The look they give the bird that sits on their windowsill as if someone dared give it permission to sit there. Rude bird. The subreddit r/MildlyStartledCats knows what we're talking about.
It's that cat look that you, as the owner of said cat, cannot help but laugh at. I mean, cats are always hilarious, that's kinda their thing. They're silly and have a tendency to zoom right into the wall sometimes. But what makes them special is that, really, even their very mild confusion by simple, totally normal things, is hilarious to anyone who loves cats at all.
