I have been asked many times by people who are about to adopt a cat "Do long-haired cats shed more than short-haired cats?"
I can answer that, no problem.
Long-haired cats shed long hair...short-haired cats shed short hair. In the end, you just have lots of hair to vacuum up whether it is short or long. I personally do not see any difference.
Shedding is related to the light-dark cycle. Cats shed in the spring to rid themselves of the winter coat and they shed in the fall to prepare for the thicker, warmer coat.
I always try to comb the cats more often in the Fall (that includes the dog, too) so their coats are in good condition for the winter. The winter coat is naturally going to be thicker so prepare to groom more and purchase a comb to rid the bloomers of tangles.
When I want to really relax I comb my cats. You can lose yourself in it and time will pass quickly. That is, if the cat enjoys it. If not, it can be quite a chore. Buy a proper comb so you do not pull the hair while grooming. The comb should have wide teeth. Always start at the head and work your way to the tail. Hopefully, kitty will be very relaxed half way through and it will be enjoyable for both of you.
