Understanding Cats’ Unique Diet:

Cats are obligate carnivores, which means their natural diet primarily consists of meat. Their digestive systems are specifically adapted to process animal proteins, and they lack certain enzymes needed to digest plant-based foods effectively. As such, their nutritional needs differ significantly from those of omnivores or herbivores.

No, cats should not eat walnuts or any other nuts. Walnuts contain a high amount of fat and protein, which is not suitable for a cat’s diet. Additionally, walnuts can be challenging for cats to digest, potentially leading to gastrointestinal issues.

If a cat ingests a walnut, it can lead to various health issues. The high fat content in nuts can put stress on a cat’s liver and pancreas, potentially leading to pancreatitis or other digestive problems. Moreover, the shape and size of walnuts can pose a choking hazard to cats.
