My Favourite Animal

My favourite animal is gregarious and cheerful almost always.

What he will do for company and stimulation is almost limitless, as he is happiest when in a noisy, boisterous atmosphere.

He is loving and carefree, talkative and almost always in the mood for play. He responds to stimulus with affection and excitement.

He will happily come and sit by you, but he has to make the first move always.

If only I could get him to stop taking a crap all over the house.

He loves music, preferably loud music, it excites him beyond belief.

If I reveal his coat or colour, food or favourite plaything it would give the game away.

In his own way, he speaks to me.

What is he?
