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!
This is grain and sugar free, not convinced the meat quality is the greatest but i guess for what you pay you have to expect that. I feed this alongside other grain free foods and my cats love all the flavours. One of my cats has chronic tummy upsets and has not been affected by this food. I do however only feed it a couple of times a week rather than as their sole food, so this could account for it!
