sort of. I had an 18 year old cat, he died but his fur was a cream color with gray paws, ears, tail, you get the point. Anyways when he was younger he had cream background color and brown features so I guess you could say it changed like human hair. I hope this answer satisfies you.
Sometimes, but if they already have white hair they sometimes turn to a light gray with some white too.
My cat is mostly black with black whiskers and 1 of them recently turned white. She is 11 1/2 years old. Maybe that is her going grey!
Yes, a ladybird or ladybug does change color as it gets older. This beetle can change from brown to yellow to orange or red during its lifetime.

Yes it can. As the baby gets older they change their hair colour. If you need more info look at Wikipedia.

A guitar's sound will very gradually and subtly change as it gets older if it is played regularly. Some would describe an older guitar's sound as "warmer" or "mellower" than that of a brand new guitar.
Yes. Usually it gets poorer as the car gets older.
A lab can not change color like from yellow to chocolate. However an older lab could change from yellow to white or the color of his fur gets lighter just like as people get old their hair starts to turn gray. This is because everyone's hair is naturally gray, pigments just color it. When pigments stop working or run out your (or your dog's) hair gets lighter in color. But only peoples turns gray.
