Why does it take so long to dry cat fur?

Drying some long-haired or thick-coated cats takes up to half an hour, even when using a high-quality blow dryer.

Why does it take so long?

Fur can absorb more than 30% of it’s weight in water.

“A hair in good condition can absorb more than 30% of its own weight of water. If the hair is already damaged  by other factor the percentage can reach up to 45%. Its length can thus increase by 2% and its diameter by 15% to 20%!. And its all depends on cutical and sebum of the particular hair.”

No wonder drying is the most time-consuming part of cat grooming.
