In Germany, Royal Canin is one of the most expensive foods to buy, but if it is the best - well, I rather doubt it. Felidae has a higher percentage of meat in its dry food AND is cheaper as well. Grau Lamb is better as well, however, neither do I know the price, nor whether you can buy it in Sweden at all.
Anyway, I don't think that dry food -no matter how good its quality- is good for cats. More than 80% of our household cats die of kidney problems. They are highly adapted desert animals, they don't drink a lot and normally, they don't have to drink a lot. But if you give them dry food, they must drink. A cat fed exclusively on dry food has to drink 400 ml of water each day to stay healthy. Frankly, I have never seen a cat drink that much.
As for BARF, I'd say that is good decision
... however, it is rare to feed raw food in combination with dry food. You want to be careful there and have some 8 hours interval between feeding raw and dry, lest your cats get stomach troubles. Why don't you go for good quality canned food instead?
And I'm very interested in any BARF ideas or recipes you have!
