Yes, though they like to stand around and ruminate (chew their cud) for a while first before they lay down to take a nap.
Yes.
Hours at a time, they sleep this way also.
Yes, to chew their cud.
General urban ledgend states that, when it is going to rain cows lie down.
Where do cows lie? On their UDDER side.
Elephants do not lie down and sleep. They sleep standing. You know why? They are afraid ants might get into their trunks
because theyre insensitive idiots :D
No. Cows are not capable of lying like humans are, in the context of the ability to not tell the truth. All animals, except humans, never lie no matter what people think.
"Lie down" is the correct phrase to use when talking about reclining or resting in a horizontal position. "Lay down" is incorrect in this context because it should be "lay" only when used with an object (e.g., lay down the book).
Cows only lay down when they are chewing their cud and resting after eating their fill. They don't lay down for any other reason, even when a storm or rain-shower is coming or happens. See the related question below for more.
Yes, a cow can go up stairs, although they find it too difficult to go down them :)
This is called lying down, cattle do not sit down as their bodies are not built to sit. They lie down as they are resting, cattle will only chew their cud when they are relaxed. They will also digest standing up as well.
