I feed mine on dry food, but make sure - obviously - that there is
always fresh water there for them.  I *occasionally* give them some
treaty food, like tuna fish or something, which they usually look quite
smug about.

However, my sister-in-law's cat was fed on dry food all his life, and
has developed a few health problems because he wasn't getting enough
moisture.  Mine are good at making sure they drink enough, but if you're
worried that yours won't, then I'd supplement him dry food with some wet
food once a week or so.

But I'm not a professional, so I'm sure there are other people here who
are able to give you a much more informed reply - mine is mere
experience. :o)

I prefer to feed super premium foods as well, but many cat nutritionists
agree that the worse wet food is better than the best dry food. There
are many brands out there that are not as expensive and are very, very
good. Also, bear in mind that a super premium food (like Innova,
Felidae, etc.) is more nutrient dense, so your cat will likely eat less
of that than of one made with more crappy ingredients.

I wouldn't change your brand (not that I know this brand, I'm in UK) if your
cats happy with it, drinks plenty of water and has no health problems leave
him on both.

can you not find another way of cutting back eg cutting back on something
you buy to eat! (I am not meaning to sound rude BTW!) we are all guilty of
buying 'treats for ourselves' :-)
