Purina One isn't all that bad. Nevertheless, I prefer Nutro Max Cat Complete Care. Science Diet used to be good, but after Dr. Hill died they got sold out to Colgate-Palmolive, and Iams used to be good too, but they got sold out to Proctor & Gamble. Now you see both brands in the grocery store.

Definitely a Nutro fan. Started using it a year ago for all my fur persons. Really makes a difference. I've got three cats, two Great Danes, a Jack Russell and a Jackacockapoo.

My cat gets dry kibble Nutro as standard fare. On holidays only she gets a can of goody-goody. There's some good stuff out there, and you pay $0.50 a can for it (in the pet supply store). I was particularly fond of this particular canned food called Unique. I'm not sure if its still available but it had visably discernable seafood in it (huge chunks) of various kinds. I got that and the Iams, and Whiskas too.
