And another thing i am wondering is, when you add all that water to the kibbles to soak it, do you use warm water only?
It soaks better, on the other hand water companies discourage drinking warm water from the tab because metals like copper, lead and cadmium can come lose from the waterpipes.

I was thinking of soaking the same ammount of water as the kibbles. So for 300 grams of kibbles 300 gram of warm water + all supplements for 30 minutes. So the suplements can soak into the kibbles aswell, and adding the rest of the normal temp tab water after. then feed.

What do you guys think of this?
