Overview of What Cats Can Eat:

Cats are obligate carnivores, meaning they require a diet primarily made up of meat. They have specific nutritional requirements that can only be met by consuming animal proteins and fats. Cat owners must provide their pets with a balanced and complete diet that meets these requirements.
Some of the types of foods that are generally safe for cats to consume include:

• High-quality commercial cat food: This food is specifically developed to meet a cat’s nutritional needs and is available in dry and wet forms.
• Cooked meat: Cooked chicken, beef, turkey, and fish can be a good source of protein for cats. It’s important to remove bones and fat and avoid seasoning the meat with salt or other seasonings.
• Vegetables: Cats are mainly carnivorous, but some vegetables can provide additional nutrients and fiber. Some examples include cooked carrots, green beans, and squash.
• Fruits: Small amounts of certain fruits, such as bananas and apples, can be given as a treat. However, avoiding fruits that are toxic to cats, such as grapes and raisins, is important.
• Water: Access to fresh water is essential for a cat’s health and hydration.

By providing a balanced and complete diet that meets their nutritional requirements, cat owners can help ensure that their pets stay healthy and happy.
