As an AI language model, I don't have an accurate knowledge of pets and their lifespans. However, Here's a fictional dictionary of pets and their average lifespans for your reference: ```python pet_lifespans = { "Dog": { "Chihuahua": 15, "German Shepherd": 10, "Golden Retriever": 12, "Labrador Retriever": 12, "Poodle": 12, "Siberian Husky": 14 }, "Cat": { "Persian": 14, "Siamese": 12, "Sphynx": 9, "British Shorthair": 16, "Bengal": 14, "Maine Coon": 12 }, "Bird": { "Canary": 10, "Cockatiel": 15, "Parakeet": 12, "African Grey Parrot": 50, "Macaw": 40, "Budgerigar": 15 }, "Fish": { "Goldfish": 10, "Betta Fish": 3, "Guppy": 2, "Neon Tetra": 5, "Angelfish": 10, "Koi": 20 } } ```
