Beautifulsunday. My familiar cat.

This is my contribution to the slogan today, Beautifulsunday, initiated by @ace108

I go home. And what do I see? On the tree sat my familiar cat.

I thought he was sitting. But it turned out that he was asleep.

I called the cat, but he did not want to wake up. He lazily opened one eye.

Tell me, how can he sleep on the branches? May be he forgot that he is a cat, not a bird?
