Oranges are a healthy part of a human’s diet, but if your cat is interested in this juicy fruit, can you share it with your feline friend?

Citrus fruits, such as oranges and grapefruit, though, are not recommended as they contain oils that can be toxic to cats. Read on to find out more.

Oranges: Nutritional Facts

Looking at the nutritional makeup of a standard orange, it is clear they are very low in protein. They also contain very minimal fat but are quite dense in carbohydrates for their size.

Cats are highly dependent on protein and need a high proportion of this in their diet. They also tend to use fats as an energy source rather than carbohydrates. This means that oranges are not particularly nutritionally suited for cats.

We can see that oranges are an excellent source of vitamin C, potassium, and fiber. Cats do require fiber to help with healthy gut function, but because cats are carnivores, they do not digest plant material particularly well.

Therefore, it’s best to gain fiber from other sources. Cats also produce their own vitamin C, so this is not useful to them.

Oranges also contain various oils, mostly in the peel and seeds, but also in the fruit itself. These oils (namely d-limonene and linalool, but also alpha-pinene, citronellol, geraniol, and others) are toxic to cats because their bodies cannot process them, especially in higher
