Yes, I think so. As the article says, it is non toxic and can only help. With a LARGE cat... the requirement for the taurine would be higher.

For humans you know, Taurine is used now in insulin resistance when inositol is used to help blood sugar levels. It also improves bile flow in humans, as well as provides the other necessary benefits. It is very inexpensive. But if you are in Canada, it might be hard to buy...maybe your Vet would sell it to you or at least give you an RX so you could buy it? The last I heard Canada required RX for single amino acids. I don't know if that is still true or not.
