Suggest a cat food for my cats

[Snickismylife]

NEVER EVER feed your babies IAMS. A few years ago pamela Anderson did a video on IAMS and they do test on animals it was small cages with multiple cats and dogs with chunks of bodies missing out !!!! That day I threw out all the IAMS in my house and went to purina

I've been feeding Fister Royal Canin's "Mobility" and "Senior" for quite some time, and he gets a bit of "Sensitive" too. On the bags it says: Vetenary Exclusive. I cannot buy it in ordinary pet shops, only at the vets. Fister seems to thrive on it. I do give him a bit of Whiskas wet food, the one in pouches that has gelé in it. I pour a bit of boiled water in it also, since he licks the juice off and mostly leaves the rest.

I would like to try some of the grain free, but I have not seen it here. In this link (thanks again, Freedom!) it does say which ingredients are in it, but not what age the various products are for. Fister is 15 and I believe he should not have too much protein. Is that right?
