Hi. I like animals very much. I have got three pets at home. They are: a cat, a dog and a gold fish.
My cat`s name is Murka. It is two years old. It is grey and white. Its eyes are green and its nose is pink. Its tail is long. Murka often plays with a toy mouse. The cat likes meat and fish.
I have got a big dog. His name is Ders. Ders is 4 years old. It is really big and beautiful. My dog likes running, jumping and playing with me. I throw a ball and Ders brings it to me back. I really love my dog very much.
My gold fish is small. It is yellow and orange. It enjoys playing with other fish. My fish eats food for fish. It doesn`t like darkness. It is only 5 months. (Ей 5 всего месяцев)
I like all my pets but I would like to have a hamster too. 
Привет. Я очень люблю животных. У меня есть три домашних животных дома. Это: кошка, собака и золотая рыбка.Имя моей кошки Мурка. Ей два года. Она  серая с белым. Ее глаза зеленые, а нос розовый. Её хвост длинный. Мурка часто играет с игрушечной мышкой. Кошка любит мясо и рыбу.У меня есть большая собака. Его зовут Дерс. Дерсу 4 года. Он действительно большой и красивый. Моя собака любит бегать, прыгать и играть со мной. Я бросаю мяч и Дерс приносит его мне обратно. Я действительно очень люблю свою собаку.Моя Золотая рыбка маленькая. Она желто-оранжевая. Она любит играть с другими рыбками. Мои рыбки едят корм для рыб. Они не любят темноту. Моей любимой рыбке всего 5 месяцев.Мне нравятся все мои животные, но я хотел бы ещё иметь хомячка.
