I've noticed recently that my cat Sadie hasn't been chewing her food. I get the Iams Weight Control cat food with the little pieces. She'll take a piece of food in her mouth and wash it down with a gulp of water. I tried getting her to eat Whiskas cat food the other day, and those pellets are much bigger. She tried eating it, but started complaining and spit it out. I wonder what's wrong? She hasn't been acting differently otherwise. She's the same lovable cat who loves to play, so I don't think she's sick. But it still has me curious and worried.
