Oh dear I'm not too surprised about the cat hair sticking. They probably think your growing the plants specially as a treat for them. Dogs have owners, cats have servants type of deal lol.
I find I have to tie my hair up before going into the girls now as on a couple of occasions I spotted hair draped around the tops. My husband even finds my hair in his tabacco and grumps thats its the worst tasting s**t ever, and has threatened to make me wear a hair net (!) in case it gets into the harvest.
