If you have an opportunity get some Wellness and try it. That stuff
smells really good and is one of the best quality foods I've found. I
also like Felidae and Innova, and Precise isn't too bad either. Solid
Gold makes a tuna canned food that is great for treats but I wouldn't
feed it regularly. And they all smell really good!

....all of which are "all life stage" foods which shouldn't be fed to senior
cats (or adult cats, for that matter). Higher phosphorus, sodium, calcium,
magnesium levels, you know!
