First Answer:
No. Fur (hair) is one of the requirements of being a mammal even if you shave every hair off your body. Every mammal is born with hair follicles, which makes them mammals. You might think that whales don't have hair on their body but they do have small hairs on their body. There are over 80 species of whales, and the hair is only visible in some. Whales have hair on their heads as fetuses, but they don't always keep it.
Second Answer:
Yes. Whales may have some form of hair at some point in their lives, but as such it is not "fur". If a hair follicle counts as fur, then human tail bones would count as tails.
There are also cat breeds that have no fur, and are also regarded as hairless.
Humans themselves have no fur, but hair, and there is a difference in type by some accounts, and certainly a difference in word usage.
Dolphins have no fur, nor could they be refered to as haired animals.
While such obvious characteristics as "furriness" or "hairiness" may help the layman identify a mammal, it is important to realize that there is no hard and fast easy rule.
For instance there is the classic joke of the professor who asked a young man to explain what set a mammal apart from other lifeforms. The young man said "They give milk and have fur.", to which the professor replied, "So does a coconut!"
Thus while some authorities go to great lengths to "find fur" or "find hair" on any animal that has been classified a mammal, it does not always work well, or at all. If one wishes to define a whisker as a hair, that is one's freedom, but one looks silly when presented with a catfish.
Or one can speak of some hair or fur at some part of the pre- or post-birth : shortly worn and quickly lost, much like a vestigial tail in a human fetus. This could make an animal able to be called "furry" or "hairy", but again, no more than you could call a human "tailed" for it's fetal tail or the coccyx (tail bone).

No. Mammals are the only group of vertebrates to have fur.
Dolphins have hair when they are born but lose it shortly afterwards.

Mammals are different than other animals for a few reasons, but the main one is the presence of hair or fur. Another reason is that mammals have mammary glands.
Fur and hair helps animals even though they Arte warm blooded to keep warm
In general they are called mammals.
The group of animals with fur or hair is the mammals.
Guinea pigs are mammals. All animals with fur and give milk are mammals.
The presence of a backbone (a "vertebrae") does not DEFINE a mammal because other animals also have backbones, eg reptiles, birds and fish - these animals are also "vertebrates".Mammals are mammals because they are the only animals to have fur/hair and feed their young on milk.
There are few different types of groups of animals that are warm blooded and have hair or fur. The largest group of warm blooded animals are tigers and coyotes.
yes, all mammals have fur (fur can also be called hair, in human's case)
