At one point my mom had 4 long haired Himalayan cats. So, I'm sure what dealing w/ is minor, in comparison to amount of hair and dander in her house. I used 2 of the previously mentioned suggestions. Tape & Rubber gloves. They both work well. The rubber gloves worked the best, overall. I found that lightly misty them w/ a little H20 improved the method.
Now, to really keep a handle on things I strongly recommend trying to do the following. 1) brush cats at least once a day (the soft silicon brushes do a great job). 2) Vacuum carpeted areas and/or furniture daily or every other day. Not only will this cut down on hair build up, it decreases dander and saliva in the air that can multiple health issues.
