I live in a block of flats. My flat is on the fifth floor. There are three rooms in it. We have got a living room and two bedrooms. My favourite room is my bedroom. There is a kitchen, a bathroom and a balcony in our flat too. There is a lot of furniture in all the rooms: tables, chairs, armchairs, beds and sofas, wardrobes, bookcases and carpets. There are beautiful paintings on the walls. We have got a fridge and a cooker in the kitchen.

Tom, aka Thomas, is a short-haired cat of an obscure breed, with white paws and a light chest. The main character and the main villain of the series. Despite his obvious predation, it is Tom who most of all gets the first number. The main goal of Tom's life is to capture the harmful mouse Jerry. Secondary goals are: eat well, sleep well, and generally lead an idle lifestyle. In a number of episodes, the essence of Tom's heartfelt claims to a cute white cat is revealed. Tom has his own mattress basket and is a completely domestic cat.
