I want to tell you about my cat, whose name is quite usual - Murzik. I picked it up on the street really tiny kitten, when walking home from school. Despite its size, this tiny nubbin had a very loud voice, and ate so that soon became like a fluffy ball in a thin tail. Cat very long time why didn't grew up, and we have already decided that it seems he has some miniature breed, but at some point he suddenly turned into a large, handsome cat with brilliant green eyes.

My cat is very affectionate, funny and smart.

He always somehow know when I come from school. When the door opens, he runs to meet me, rubbing on my feet and meow loudly, as if says how much he missed me.

He likes to play hide and seek with me and catch-up and always finds me, no matter where I was hiding. In the morning the cat is the first one up and tries to Wake anyone, so he asks to be fed.

My cat, not just a domestic animal, a family member, and I really love him.

It's late and I should go to bed, that's my favorite Murzik, as usual, is also laid on the pillow next to me, purring loudly. Good night, cat! Tomorrow is a new day.

When I was 5 years old my parents gave me a cat. It was white with gray stripes, that is why I gave it a name after my favorite cartoon character - Matroskin. I grew up with my cat. We played together, Matroskin even slept in my bed with me. Once we went to the village, my cat never left the garden, but that time he got lost. I searched for a long time, but failed to find him. I cried a lot because I missed him and was frightened to imagine what happened to him. I week later our neighbors called my dad to tell us that Matroskin came back and was trying to find his masters. I have never been happier than when dad brought him back home.
