Hi, does anyone has experience with Iams dry cat food?

Recently I tried this food, my cat seems to like it very much. But I kinda noticed she drinks more water and did not poop every day like before. Otherwise, she is still active and playful. I checked the percentage amount of fibre is somehow lesser than other brands, but ash is much higher (10-11% iinm).

I read around, Ash is a group of minerals that includes magnesium. It is something to note if the cat has a digestive or urinary tract problem. And usually, the amount is below 10%.

Right now I am not sure whether I should continue giving her Iams or not?

Protein at 29% is it good enough? Compare to other brands with at least 30% or higher.

Thanks
