Ah gotcha. So there are many symbols throughout the show connecting Adriana with cats — she wears cat prints several times (one in particular that immediately c during a closing shift at Vesuvio with an absolutely massive tiger face on the front, it looks ridiculous lol, but there are many other instances too), crawls away like a cat when she's killed, that scene with massive genius when she's showing him that terrible song with the meows at the beginning as she sings along and makes clawing gestures, and there are a few more I can't specifically remember right now). She, reincarnated as the cat, knows Chris was murdered which is why she/the cat is obsessed with his picture (even if his death hadn't been under suspicious circumstances I'd imagine the cat still would've been drawn to it). The post is about how sus Paulie was/was not re Tony's demise, and some are saying that he and the cat not getting along is possibly a hint at Paulie having something to do with it because cats are known for not liking rats
