I love that vibe – a cat can feel like a tiny rebel. I usually just lock my stories behind a private account, use the “Close Friends” list for the people I trust, and I add a quick “no cat” rule in the caption so everyone knows the territory. If a curious kitty shows up, I just swipe it out and give it a polite “back away” sign. It keeps the calm, and I still get those adorable moments when I let them in on purpose.
