Jamie just finished his food
! I'm an expert on rotating, because this cat insists on as much variety as possible (as long as it's [ultra]premium brands). I even have to make up meal plans for my husband or the sitter to follow when I'm/we're away. JC automatically stops eating a particular food after about three months, and doesn't want to eat the same food more than twice a week. Lately I've read several articles in cat magazines recommending rotating foods, provided the cat doesn't have a sensitive stomach. Supposedly you can avoid nutritional deficiencies that way.
I'm definitely in favor of feeding more than one brand. My family is now living in Nebraska, and a few years ago the snow/ice was so bad that the stores weren't getting in new supplies. My mom's cat (quite old at the time) only ate one particular type of canned cat food, and when my mom ran out and couldn't get it anywhere, she had to call up everyone she knew (and everybody they knew) to scrape together enough cans so that Ginger wouldn't starve. I still remember getting a fax that said,"The brother-in-law of a guy down the street has ten cans!" My mom now stockpiles dog and cat food.
I just noticed that the Prairie food is made in Nebraska, so if JC decides he likes it, I'll smuggle some back with me this summer. Thus far there only seems to be one importer here in Germany. I'd like to try the dry, but the bags are so big. Though I suppose the local shelter will take it if he doesn't like it.
