Ours always used to eat exclusively eat Science Plan dry food (sounds good, I ate some once, really not so good if you're human-shaped). Then LMC had all her teeth removed and we weren't so sure she'd get adequately nourished with dry food alone (she's the teeniest cat, never really reach escape velocity from being a kitten) so give them a pouch of wet food once a day. Turned out that LMC will still happily chomp the dry stuff, but they're now both mad keen on the wet stuff. They mostly eat the Purina Gourmet (oh I know), though I say eat, they lick off all the gravy and mostly leave the rest. You can just get the gravy. You know what happens when they put that out. It's not a question if you have cats.
There are some Thrive (I think) 'real' chicken and fish in cans that they love like crack, but it costs more than fillet mignon. So I keep that back as a treat.
