As you can see olives contain a little sugar and carbohydrates, a huge amount of acidic content, water and salt, a hint of phosphorus, a little calcium and a large amount of fat.

This means that olives are not a good food for cats to eat. This is due to the huge amount of acidic content, water, and salt that they contain. They are just not good for cats to eat at all. If they were to eat one or two then do keep an eye on them to make sure that they are okay. If they were to eat a lot of them they would need attention from a veterinary surgeon due to the ill effects that they would have on a cat.

They also do not have any nutritional benefit for a cat either.

Eating a lot of them will cause them to be sick unfortunately and so they should be avoided as a food.
