Paws Off! The Dangerous Foods You Must Avoid for Your Pets
6. Cashews: Cats and Dogs

Regarding nuts, opinions vary on whether they are safe for pets, with the exception of Macadamia nuts, which should always be avoided. It's generally advisable to refrain from giving nuts to pets since they are high in fats and oils, which can lead to pancreatitis or contribute to obesity and related health issues such as diabetes and joint problems.
If you decide to treat your pets with cashews, do so sparingly and choose unsalted varieties. While they aren't inherently harmful, they shouldn't be a regular part of your pet's diet.
