Why Does My Cat Glare at My New Puppy?

So, I brought home a new puppy last week. Cue the dramatic music. My cat, Luna, has always been the queen of the apartment—her throne is the couch, her loyal subject is me. But now? She’s been giving me the coldest stares, like I’ve committed some unspeakable betrayal. Every time I pet the puppy, Luna sits just out of reach, tail flicking, eyes narrowed. She’s started knocking things off shelves again (her signature protest move). I swear she’s plotting a coup. Is this normal? Do cats get jealous, or is she just mad I brought home a drooling, clumsy furball? I’m trying to give her extra attention, but she acts like I’m invisible. Anyone else dealt with this? How long does the silent treatment last? Tips for peace negotiations are very welcome. #PetDrama #CatVsDog #JealousPets #Pets
