These guideline amounts are a starting point and your cat may need more food depending upon age, activity and temperament. In order to reach optimal body condition, you may need to adjust food intake. This represents the total recommended volume of food per day. You should divide the total recommended feeding amount by the number of times you feed your cat per day to get the actual portion size per feeding.

Rated 2 out of 5 by from Weird Shape. Round Ball cat food. My cats do not enjoy this at all I was trying to transition over to this food for the weight control benefits. I have a 17 pound cat who will any cat food. From orijen to store brand. She will not touch this. I think it has a lot to do with the round pellets. Also this food has a good bit of corn in it. Overall I will not purchase this again.

Rated 5 out of 5 by from Kitties Love the Shape of Food We own six indoor cats.They are all very healthy, thanks to IAMS! We have some senior cats with the oldest being 15 and 13 years old. They act as though they are still young cats. Our other cats are young adults.One thing is for sure. Our cats most definitely prefer the small round shaped morsels as is sold in this particular IAMS food. They do not seem to want to eat the triangular shaped food.We are very happy with IAMS!! All our cats have a good weight and shiny coats.

Rated 5 out of 5 by from Great Product with a Great Deal Wow, iams! My cat loves your product! She just can't stop meowing for more! Her food is alway unabandoned, and even my dogs like it better that their iams food! I recomend this cat food to anyone with a middle aged cat, and even people with kittens! It is a great product. I will not but anything else. I could tell the difference when we switched food after we bought her. It is excelent, and my cat is very active, espesially after meals. The iams weight control proactive health is a product for every cat of just about every age and I know that if my cat lives long enough so that she won't always eat it, another package of iams cat food is the only replacement that would be fit for my cat. And any other brand is out of the question completely. No one is convincing me to get another brand.
