Always in you, Sometimes on you;

If I surround you, I can kill you.

What am I?

If I remove one from eleven it becomes Ten and if I remove one from nine also becomes Ten. How?

They came out at night, without being called.
They lost at day, without being stolen.
Who are they?

I have a head like a cat and feet like a cat, but I am not a cat. What am I?

I came first on earth but second on the heaven.
I also came twice in a week but found just once in a year.
I stay away from months but you can find me in February.

What am I?

I’m orange, I wear a green hat and I sound like a parrot. What am I?

I possess a head

I flaunt a tail

But I don't have mouth or legs

Can you find out who I am?

If eleven plus two equals one, what does nine plus five equal?

My first is in chocolate but not in ham. My second is in cake and also in jam. My third at tea time is easily found. Altogether, this is a friend who is often around. What is it?

I look flat, but I am deep. Hidden realms I shelter. Lives I take, but the food I offer. At times I am beautiful. I can be calm, angry, and turbulent. I have no heart but offer pleasure as well as death. No man can own me, yet I encompass what all men must have. What am I?
