i have a pet. it is a cat. it*s name is vas*ka.  he is a real member of our family. vasiliy is a very clever cat  he always looks at me attentively when i speak to  him. i  know that he understands everything. we like to make something plesant for him: my mother buys fresh fish, my sisster gives him  fur toys  to play. vasya is four years old but he is very  energetic. he likes to run and jump as a little kitten. we love our cat very much!
