Isabelle and Diesel both love fish - way more than any other raw combo including rabbit, venison, chicken etc! At the moment at each meal they have approx 35-40g of NI raw mixed with a teaspoon of Applaws tuna selection - just to get them interested! I've seen a couple of threads saying that too much fish is bad, especially tuna. Am I feeding them too much tuna? Could it be dangerous? I have also bought some frozen Coley chunks - do I cook this or can i give it to them raw? I don't want to do the wrong thing!
