I know there are some people that have a problem with Science Diet but I don't remember exactly why.

All I know is that this is the only food T & P have gotten their entire lives with me, and as you know they are both a healthy 17 and almost 15 years old, so whatever is supposed to be wrong with Science Diet can't be that bad.

I started Tubby on it shortly after I got him because he had dandruff. The vet said a "premium" food has more oils in it than the "store bought" brands, and the extra oils would be good for his skin and help the dandruff. Well, since he has had dandruff his entire life, I can't say as it helped in that department, but then again, I don't know how bad the dandruff would have been with a "store" brand.

But even though it didn't stop the dandruff, I continued to buy the Adult formula for quite awhile. Then I switched to the Feline Maintenance Light for many many years to keep Tubby's tubbiness under control - and it worked because he never gained anymore weight after that. He didn't lose any (I think), but he didn't gain it either. Then, just a few years ago, I switched them to the Senior formula.

When Tubby was diagnosed with his early stages of kidney failure, the vet asked me what I fed him, and he said the Senior formula was "perfect," so that's what it's been ever since.

So, I've never done any research or anything like that, just went on the Vet's recommendations, and I have 2 healthy senior cats to show for it.
