Instead of cat-and-mouse it's cat-and-hamster--the classic cartoon tricks with some quite funny twists. Felix the cat and Long John Silver the parrot live ""in a little old-fashioned house"" with a stereotypical story-book Grandma in long skirts and shawl. Then Granny brings home Mustapha Biscuit (""I must have a biscuit""), the hamster, and Felix dreams of ""hamsters on toast, hamsters with ketchup, and grilled hamsters with gravy and vegetables."" When Granny goes off shopping, Felix tries to pick the lock on Mustapha's cage--but while he's preoccupied with the task Mustapha plucks the hairs from his tail, to make a sleeping nest. ""Serves you right,"" laughs Granny on return, but then she takes pity and knits Felix a bright, striped tail sweater. Now a laughing-stock among the alley cats, Felix goes for revenge during Granny's next shopping trip; but the second attack, which has all three animals leaping and flying about, ends with Long John and Mustapha peacefully sharing the hamster cage and Felix stuck in the parrot cage. This time he needs knitted wrist and ankle cuffs to cover the damage, and the alley cats again howl with laughter. We leave Felix plotting a ""terrible revenge."" Ambrus' audience will laugh too at Felix' ridiculous striped tail and hammy antics.
