Caveat: I don't have cats, nor do I know much about them.

So why am I posting here?

The company that makes my mutt's favorite food (Terra Canis) also makes a premium cat food, Terra Faelis:

http://www.terrafaelis.de/index.php

This is a small company in Bayern, DE that ticks my canine 'must haves': Lebensmittel quality, named meat source and parts (venison muscle and heart, for instance, instead of just the name of the animal), a grain free line, ethical production, etc.

A quick look shows that Taurine is indeed added to the cat food.

Terra Faelis can be bought here in Switzerland at Meiko or Zooplus (both .ch and .de)


I'm quite a fan of the dog food so I'm tossing out the cat food info, in case you might want to look into it. But as per the caveat above, I don't know much about kitties.

Another premium cat food possibility is Gina and Fritz, a small Swiss manufacturer. Looks like they do not add Taurine, though.

Wishing you and the kittens all the best...
