As you can see spinach contains a little carbohydrate, a huge amount of acidic and water content, quite a bit of salt and phosphorous, a lot of calcium, and a hint of fat and sugar.

This means that spinach is not a great food for cats to eat due it’s huge water and acidic content. They can nibble a little of it but if they eat a lot of spinach, it may cause them problems. Just one or two leaves is more than sufficient for them.

This goes for cats of all ages from kittens to senior cats to pregnant cats.

Certainly any spinach that is fed to them should be washed before hand so that any dirt or grit or even pesticides are removed before feeding to them.

Cooked or raw spinach?

They can eat cooked or raw spinach. Obviously, cooked spinach should be properly cooked but they should only eat a small amount of whatever is served for them.


In summary,  spinach is not the best veggie for cats to eat and there are certainly better fruits and veggies for them to eat such as zucchini which will serve them much better.
