My favorite animal - a cat. Cats have many, but none, I think there is such a wonderful,like I did. Her name is Dasha, cute. She was about three years.
Her coat tricolor, striped. Older people say that cats with such color to bring good luck.Ever since the-cutie Dasha appeared in our home, fun and laughter never leave us. Weare constantly in the affairs of pitomitsy: chasing a paper bow, then a ball of yarnunwinds, it ensures that both lay the table.
She has expressive green eyes. It's funny to watch, as they rounded up when the cat is surprised anything. If the Dasha-cutie feels a new smell or hear a new sound for her, herwhiskers are long and her eyes are big and beautiful, she navostryaet ears and closely monitored.
She not only loves to run and play, and sleep, soak up the sun. When Dasha-cutie wantsout, she meows. Having wanted to eat, she fondled. If we sit there, she can quietly take anything off the table.
That is such a wonderful cat living in our home. I love her very much.
