Read the text. Are these statements true(T) or folse(F)?
Most people in Russia love animals. A lot of them have got one pet or more, even in bi cities. One survey shows that 45 % of Russians have cats at home. People like cats – in Moscow there is famous Cat Theatre and it is always full. Dogs are popular too – 36 % of Russians have dogs and there are dog shows all over the country. The shows have prizes for different types of dogs. There is also a dog show programmer on TV. Wild birds were once very common pets in Russia. Many people had wild birds from the forest in their homes. They freed the birds in March and April every year to celebrate spring. Now only 12 % have birds as pets – these are mostly budgies. Goldfish are less popular now, too – only 4 % of Russians have them as pets. And 10 % of animal lovers have other pets. Some of these are small, friendly animals such as hamsters and rabbits. Others are dangerous or rare pets like spiders, for example.
