Using a fabric softener such as Febreze while doing your laundry will help with keeping cat hairs off your clothes.
Is there a natural way I can prevent cat hair from sticking on my clothes? With a natural spray or something?
If your cat sheds to much you can try taking it to the vet for a cheap price and have the hair cut or have it somewhat shaved, it usually deals with the probelms of cat hair getting anywhere. And I do not recommend using any sprays of some sort.
No not really. Using chemical sprays to attack problems like this is a bad idea. If you vacumn daily inc your cats bedding and brush him/her daily there should not be such a big problem but getting a lint roller or using a strip of cellotape on your clothes will bring them off.
I'm not to sure if it's natural, but a lint-roller might help. You can get it for a cheap price at a lot of places. :) Hope I helped, good luck ;)
