Can Cats Eat Nuts and Seeds?

Nuts and seeds are excellent sources of plant-based protein, healthy fats, and other nutrients. They’re a superfood that should be part of a healthy diet. But are they also good for cats? Can cats eat nuts and seeds?

Felines are carnivorous beings, so they get most of their nutritional needs from meat and don’t need to rely on plant-based foods. Moreover, nuts and seeds are dense in fat which is bad for cats. Not only that but some nuts and seeds can also be toxic to felines.

Let’s dig deeper and tell you everything you need to know about feeding your cat Nut Fruits and dry seeds.

Can Cats Eat Nuts?

Nuts contain protein, fiber, and healthy fats. They help provide the human body with good fats such as Omega 3. The human body does not fully absorb the fats in nuts, so they don’t usually result in weight gain.

However, the amount of fats in nuts is too high for felines as they are much smaller than humans. So, feeding nuts to cats can cause weight gain and a high risk of diabetes. Nuts can also be a choking hazard for cats, making them dangerous for kitties. As per ASPCA, avoid feeding nuts to cats because it can cause digestive issues. Therefore, nuts are not recommended for cats, and they should not eat them.

Is It Safe for Cats to Eat Nuts?

The safety of nuts for cats depends on what kind of nuts they are given. Some nuts come with coatings causing gastric irritation and may also damage the gastrointestinal lining of cats. Although this does not happen with all nuts, it is still a risk.

Some nuts lead to toxicosis, causing severe cat reactions like irregular breathing, diarrhea, vomiting, and liver dysfunction. Nuts poisoning in cats can also cause digestive upset and pancreatitis. Pancreatitis is a condition where the pancreas of the affected cat becomes inflamed.

Even nuts that are safe for cats should not be a regular treat. Moderation is key. Be careful about the amount and type of nuts given to the cats. If given in the right amount, nuts are a great source of protein and fiber for cats. So, make sure you do not overfeed your cat nuts.

Important to Know! What Benefits Nuts have for Cats?

While cats should not generally eat nuts, some are safe for them and can be beneficial. Let’s discuss how nuts like pecans and cashews benefit your kitty’s health.

Here are some advantages of feeding nuts to your feline friend:

  • Protein: The ideal cat diet contains around 40-50% protein. Cats have a higher protein digestibility which makes protein even more suitable for cats. So, foods rich in protein are good for cats. Since most nuts and seeds are rich in plant-based proteins, they are a good source of protein for cats.
  • Fiber: Nuts are a good source of fiber. Feeding a few nuts can be a good source of fiber for cats. This aids in digestion and improves bowel movement.
  • Vitamins and Antioxidants: Nuts are also loaded with vitamins, minerals, and antioxidants that help boost immunity, counter fatigue, stimulate appetite and improve overall health.
  • Healthy Fats: Fats are not good for cats, but that does not mean they don’t need fats. Cats need around 20% fats in their diet to maintain a healthy body. However, you need to make sure that they are getting healthy fats. Nuts contain good fats that reduce inflammation, improve heart health, reduce bad cholesterol, increase bone density, etc.

What Kind of Nuts Can Cats Eat?

Almonds are a great source of healthy fats, protein, and fiber which is good for a cat’s health. So, are almonds safe for cats? Yes, they are. Almonds are not toxic for cats; according to ASPCA, they are 100% safe.

However, since they are not a typical part of a cat’s diet, expect almonds to be of little nutritional value for your cat. They can cause vomiting, diarrhea, and possibly pancreatitis if consumed in large amounts. With this in mind, giving an almond or two to your cat is harmless.
