Basil Nutritional Facts

Basil is not toxic to cats, but eating large amounts might cause stomach upset.

The nutritional benefits of basil for humans are obvious. It is very low in fat and cholesterol, whilst offering a good source of fiber, protein, and a whole range of vitamins and minerals.

But is basil as healthy for cats? Sadly not, as cats cannot digest plant material well enough to extract all the goodness from this leafy herb. Cats are obligate carnivores, they rely on meat for their nutritional needs and their gastrointestinal system is highly adapted to digest meat.

Cats, therefore, do not digest plant material well, meaning they do not extract all the good nutrients particularly well.

Benefits Of Basil For Cats

Although cats are not well adapted to digest herbs, vegetables, and other plant-based materials, they may be able to absorb small amounts of nutrients from the fresh leaves. This healthy herb provides fiber, protein, antioxidants, vitamins A, C, K, and more, and plenty of minerals such as calcium.

    Why does my 1 year old kitten chew on wooden cabinet door corner and a small tall table’s corners?

      Hi Jo Anne! It’s possible that your kitten is feeling some discomfort from teething and chewing on things helps relieve some of that. You might try giving him a teething toy for kittens or something like silvervine sticks. Silvervine is like catnip, so it may be more appealing to him than a plain old toy. Hope that helps!
