Meow Mix Indoor Formula Cat Food Review

My 3 adorable cats used to just LOVE Meow mix dry cat food. That was the only kind they'd eat. But I've noticed over the last year or so that they don't seem to like it as much. 

As a matter of fact I took in a stray cat and fed him Meow mix last year and he just loved it, then he "disappers" for a few days at a time and comes home starving. So he used to dive right into the meow mix and purr especially if he's been gone for more than a day or two. But now he doesn't seem to care for it so much.

I wonder if Meow Mix has cheapened their recipe??? Anybody else have the same problems? If so, please recommend a dry cat food that they would like. Thanks so much!
