One of my cats recently gained some weight without my realizing it.

He's old. Doesn't move around much. never has. Has hairballs. So I put him on a hairball dry food maybe 8 months ago.

I recently checked, and the hairball food definitely has more calories than his old.

And it smells sweet.

Now the back says it doesn't have any sugar in it. But I don't understand how it can smell sweet if it doesn't. I'm suspicious.

And cats can convert sugar to fat.

Anyway the hairball food really helped with the hairballs so I bought a weight management food and I mix it 50/50 with the hairball food.

Still seems to work and cuts out the extra calories.

Hasn't lost weight but stopped gaining it.
