My cats didn't really like these sachets. It doesn't seem to me, however, that this is poor quality wet food. In any case, my cats certainly didn't have any trouble digesting it. I think it's more a matter of taste.
Goes down pretty well and no sugar means it's good for his teeth (and belly). Only criticism is that the pouches seem to hold a bit less than 100g, so meal times aren't always equal portions unless you open another pouch!
My cat used to be disinterested in wet cat food til she tried this. At first i was very happy as I like the box so dont mind it hanging around in stacks in the kitchen unlike the posher brands that look like Muscleman protein powder packs. However when I compare the crude protein values of this to dry food I worry. I wouldnt mind if she would eat her 'worthy' (expensive) dry food too but now she only demands this. I love that it has no grain or sugar and a charming old school box but..
