My name is Mary. I have got a cat. His name is Alex. He is very kind and friendly. Alex is a black cat. He has got big teeth
and thin legs. Also, he has got a small nose and a short tail. He likes to sit on my knees. Actually, it was my idea to have a cat at home. I feed my cat properly and regularly. Sometimes I take him to the vet. I like to play with my pet.
