I've recently read in a magazine that olive oil is not only a healthy addition to human food, but also highly recommened for cat food...

Has anyone ever tried to add olive oil at a regular basis to their cats diet?!

I really wondered wether it is really healthy to give it to a cat daily...I am thinking of digestive problems...in the article were no recommendations about how much to give them and how often...
Any experiences here?

Someone who's adding olive oil to their "Tortellini cats" ' food???
