Eating large amounts of spinach can be problematic, especially for cats with urinary or kidney problems.

Is Spinach Used in Commercial Cat Foods?

Yes, there are some commercial cat foods that contain spinach, included for its health benefits of vitamins, minerals, and antioxidants. However, as cats are carnivores, most commercial cat diets are made up mostly of protein sources such as meat and meat derivatives.

Fruit and vegetables are generally not well digested by cats, and so are usually not a major proportion of a feline diet. Large amounts of spinach can also be problematic for certain cats, so it is only ever found in tiny amounts in commercial diets.

Is Spinach Bad for Cats?

Spinach is not toxic nor poisonous to cats, but it can cause problems if fed in large quantities, or if your cat has any pre-existing urinary or kidney disease. Spinach contains a compound called calcium oxalate, which can cause stones to form in the urinary tract (either bladder stones or kidney stones), if eaten in large amounts, or if your cat is predisposed to urinary problems.

Raw spinach has the highest concentration of calcium oxalate than overcooked spinach. Small amounts of calcium oxalate will not be a problem in healthy cats, but if your cat has any known urinary problems it is recommended to avoid feeding spinach.
