What was the name of the Flintstones' pet saber-toothed cat?

The Flintstones' pet saber-toothed cat was named Baby Puss.

Baby Puss is the Flintstone family's domestic cat, a recurring part of the show's Stone Age parody. Although he resembles a large saber-toothed predator, the family treats him like an ordinary house cat. His most famous gag appears in the opening and closing sequences: after Fred puts him outside at bedtime, Baby Puss cries and scratches at the door, leaving Fred frustrated.

The character helps establish how The Flintstones blends prehistoric imagery with modern household routines. Bedrock families keep dinosaurs and other extinct-looking animals as pets, just as contemporary families might keep cats or dogs. Baby Puss's oversized fangs are therefore played for comedy rather than treated as a realistic danger.

Baby Puss is often confused with Dino, the Flintstones' purple pet dinosaur. Dino is more energetic and behaves like a playful dog, while Baby Puss is the cat. Pebbles is Fred and Wilma's daughter, and Bamm-Bamm is the Rubbles' adopted son, so neither is a pet.
