I'm in B.C. Canada and am not sure if we have Petco here - the nearest pet supply store is Tisol. I have tried Wellness, Merrick, Tech-Cal(sp?), Natural Source, Science Diet, Iams, Natural Balance Ultra, even Friskies(!), and some others that I can't remember. I do have a listing of the Top 10 wet foods (website: cats.about.com) but the trouble is Annie will NOT touch any canned food except FF. Maybe I should try again mixing FF with one of the above, but I don't have much hope - it didn't work before, she just ate her dry food instead and pestered me for treats. I have cut back on FF though, she gets a can and a half of the 3oz cans per day. Is there a premium food out there that most cats love?
