Hill's Science Diet Adult Indoor/Outdoor Urinary and Hairball Control Chicken Recipe Dry Cat Food

My cats enjoy this very much, and It definitely helps with hairballs and digests well. The fact that I have to order the 3lb bag to get the new formula is NOT GOOD! The difference between the size and shape of the old and new formulas are too great, and they hate the old formula with the big chunky pieces of kibble, they leave half bitten pieces and don't eat much. This costs me a significant amount of money not being able to get the updated formula in the 7lb bag. Everything is expensive and it's a lot of pressure.

Two 2-year old male litter mates love this kibble. No need for treats or eating incentives. Delicious, apparently.

My cat has has only eaten the urinary/hairball Science Diet cat food for 10 years. This was the one thing I could count on. When the automatic feeder dispensed the food, she took off to the kitchen. Now, the feeder is overflowing on to the floor, and when the feeder dispenses the food, my cat doesn't move. She no longer loves her food and hardly eats anything. All because of the formula change. I have tried other varieties of science diet, and even other brands of cat food, but she doesn't eat those either. I'm starting to really worry about her. They say you should gradually introduce the new food, but how can you do that when you had no idea the formula was changing, and now you can't find the old formula anywhere.

My cat has been on this food since I've had him. So a little over 2 years he is now 3. He's long haired and had only had 2 hairballs ever. They changed the recipe of the food a little awhile ago though and now all of a sudden he gained weight. He was steady same weight before that and I measure his food. This is the only thing that changed was the recipe in his diet. They did put more calories in it?
