There will be mentions of both cat hair and fur. Are there any differences between the two names, despite the common confusion?

Cat Hair vs. Fur
Humans, whales, pigs, elephants, cats, dogs, and even monkeys are all mammals, and they all have hair. The appearance, texture, and function of each species’ hair vary according on how that species has evolved.
Technically, only mammals with extraordinarily dense body hair qualify as having “fur.” Human body hair is rarely referred to be fur because of how little it is. Cats commonly have fur or body hair on them. Some kinds of animals classified as “hairless,” such as the sphynx, refer to the short, practically invisible downy hair as “hair.”
When referring to the fur that cats ingest and subsequently cough up, people sometimes call their cats “hairballs” or “furballs” in a playful manner.
You discover a cat hair, for instance, on your black sweater. “Cat hair” can be viewed as a single strand and “cat fur” as a collection. Despite being numerous, they are not grouped together like the fur on your cat would be. Pick the term that comes to mind the easiest.
Breeders frequently refer to a cat’s coat as the general appearance of the cat’s fur, which complicates matters even further. This term is almost often used in breed standards, but you may also see references to “hair” such as “longhair” or “shorthair” breeds or subgroups.
In the end, you will be in the right whether you call the fluffy, fuzzy coating on your cat’s body hair, fur, or a coat. When grooming your cat, you can either “comb its hair” or “brush its fur.”
Types of Cat Coats and Hair
All hair, including cat hair, starts in the epidermis (the layer of skin beneath), and each species of hair has a different structure. There is a muscle that is very temperature sensitive very close to the root, just below the epidermis and pores. This muscle constricts in cold weather or when a cat is terrified or agitated, giving the cat the recognizable “Halloween cat” image by making the fur nearby stand straight up. In addition to their distinctive whiskers, which are also hairs, cats’ coats can have one to three different types of hair, referred to as a “double coat” or “triple coat.”

Whiskers (Vibrissae)
The long, thick, tactile hairs that grow from the cheeks, above the eyes, the cheeks, and the outside of the lower legs are known as whiskers in cats. Due to their extremely sensitive whiskers, cats are able to navigate in total darkness, find openings, and potentially even smell things. The body language of cats may be significantly revealed by their whiskers.
Hair on Armor
Guard hairs are the longer, stiffer hairs that stick out past the “base coat” (awn hairs). Frequently, it is these hairs that determine the cat’s dominant color. Guard hairs help a cat stay dry by slowing the flow of water.

Undercoat
The undercoat is also mentioned. The softer, fluffier hair gives warmth. These are the hairs that can easily mate if a cat is not regularly maintained.
A arrow’s hair
Awn hairs vary in significance depending on the breed of cat, although they frequently make up the majority of the coat. In some breeds, like the Manx, the guard hairs are longer, although the (finer) awn hairs may be the same length in others.

Vellus
The sphynx cat has the same sparse, ultra-fine hairs as these. The human body also has vellus in all but a few areas.
Curly verses straight hair
Cats with curly hair have flattened shafts, similar to people, while cats with straight hair have rounded shafts.
Cat fur and allergies
Feld1, a little protein fragment, is the allergen that cats carry and is found in their saliva. When they groom, they transfer it to their hair, where it evaporates and dries into dander—small flakes. Because particularly long or thick cat hair would hold more dander, some wrongly think that “curly hair” is the allergy. In addition to being prevalent throughout the entire house, odor can also be found in the air, mattresses, carpets, and drapes. The good news is that cat dander allergies may frequently be controlled.
