I tried it because Ripley has a problem with throwing up easily. I didn't notice any change with him on the sensitive stomach food but he did better with Purina One Salmon and Rice. When he started having bladder infection I switched him to Purina One Urinary Care. He would still throw up but maybe a little less.

Now that I have several over weight cats I've gone to Nutro Complete Care Indoor Weight Management and every one is doing much better and hardly any vomit anymore - from anyone. Ripley still gets urinary care since he is in kidney failure but he loves the Nutro too.

Nutro isn't cheap but it's cheaper than what the vet sells plus the cats eat less of it so it last a little longer. The biggest benefits has been less poop in the litter box, it's always firm and doesn't hardly smell. Definitely worth the costs to me!
