Pet turtles and tortoises have specific nutritional needs to stay healthy. They require a balanced diet that includes a variety of foods such as leafy greens (e.g., kale, collard greens, dandelion greens), vegetables (e.g., carrots, squash, bell peppers), fruits (e.g., berries, melon, banana), and commercially available turtle or tortoise pellets. It is also important to provide calcium supplements and occasionally offer protein sources like insects (e.g., crickets, mealworms) for some species. Additionally, always ensure they have access to clean, fresh water for drinking and swimming. Consulting with a veterinarian who specializes in reptiles can help create a specific diet plan for your pet turtle or tortoise based on their species and individual needs.
