Three cats, each of which eats seven rats, won't be hungry for long.

Are the commas needed as indicated above?

Many thanks in advance.

    They are.

    The clause in red is not essential to the sentence. It is an aside and is marked by what THIS SITE refers to as bracketing commas.
    << Oops. I forgot to make the clause red earlier. It's red now. >>
