A cat cat, Coco, had no idea who the dog was after her sister and best friend, Bailey, was introduced as an unknown stranger and was actually her sister. Despite Angela's attempts to convince Coco that Bailey wasn't a stranger, she remained unconvinced. The video received over 24k likes on social media, with viewers comparing it to when their dog had a new haircut. A veterinarian advised on what to do when cats don't recognize another pet after a grooming, keeping them separate for the night and using a pheromone diffuser to calm them down.
