I have tried the Coshida tins and Opticat pouches when Oliver was smaller and much less fussy. I would say the quality is about on a par with the likes of Friskies, Whiskas regular lines, and nutritional value would be about the same also as Shiba, Gourmet Fancy Feast etc. For example for a chicken flavour the ingredients would read "meat and by products, of which chicken 4%". Which is not exactly ideal, but passable if you have many cats and just can't provide the top notch brand all the time.
