I didn't bother buying the Fishy ones, as Jameson is not to keen on fishy wet food (he prefers ''the real thing''). I just fed him Oh So Meaty Chicken and it went down really well - first time I've seen him finish a whole pouch in a long while.
I noticed the Hi Life Essential pouches are 80g as opp. to 100g - but with Jameson that won't make that much of a difference, he usually leaves the last bit of chunks for me to throw away!
