Price do at the very best tell you something about the quality of the food (the amount of meat and the quality on the ingredients) but unfortunately it's not just to check the price tag that's needed in order to tell if the food is good or not. The most expensive catfood found in Sweden contains:Cereals, vegetable protein extract, egg and egg derivatives, fish and fish derivatives, powdered cellulose, oils and fats, minerals, hydrolysed chicken protein, plantago psyllium husk
Yep, that's right. It doesn't even contain meat (except from a very small amount of "purified" chicken protein)! And the worst thing is that this food is sold through veterinaries ONLY making cat owners believe it's the very best food you can give your cat.
I really don't care if it's been proven that corn hurts the cat or not. It's been proven to be an inferior source of protein when compared to various meat meals so what excuse, except from saving money, is there to feed cats food that contain lots of corn gluten meal?
I mean, the general public don't know of it, but vets should if they decide to sell catfood.
And why drag prescription diets into the discussion? Those diets are meant for sick animals and can't be used as a norm. That kind of food should be considered as medicine.
