Top Quality = Happy Kittys!
When we adoped our two kittens at 9 mths old they had diarrhea and were often begging for scraps from our food. After an initial reluctance to eat Hill's (they over-ate once or twice and puked consequently) they got used to it and will now not have anything else and are never asking for any other food. They also eat less of Hill's compared to low-quality cat food, yet have more energy. Their poo is perfect and non-smelly. They look, feel and act like healthy kittys. If you can afford it, get it - it's actually not that much more expensive in the long run as the cats will eat less of this once they get used to it (and feel better + live longer!). If you feed only the dry stuff - just make sure you have plenty of fresh water available every day.
