I believe this is a good quality cat food brand even though it's on the expensive side, I think it's worth every penny I spend on it as my cats love Applaws as their empty bowls attest to every time. It looks and smells appealing, you can see it's proper fish or meat, not some meat derivatives like generic supermarket cat food brands, which is full of additives/sugar and fillers. Cats cannot digest these fillers.
Cats are obligate carnivores and I believe this brand and others like it provide cats with what they need and is closer to what they would eat if they were in the wild.
