Cat throwing up a lot recently? - cat throwing up a lot

I have two cats, is one of the usual weight of the other is quite overweight (about 15 pounds).

I give my cat Science Diet, but my fat cat eats too much food for my cat to the other and recently my big cat has been vomiting a lot, like all two days or less. Vomitus is basically regurgitated food, and not a strange color or so, the same color as your meal.

I was sick of cleaning and ruin the carpet. I am worried for him.

Any tips?
