All cats (bar hairless) will shed to a degree, the hair of paler cats will show up more. Moleskin attracts cat hair like nothing else.

If you're a first time cat owner stick to kittens - moggies can be just as much fun as pedigree cats . Older rescue cats can be very affectionate but they can be quite difficult - on the whole the ones I've homed have been okay, but I've had a couple who had been badly traumatised in the past.
Prepare to be woken in the middle of the night, occasionally sulked at, have furniture gouged, crockery smashed and the spot where you want to sit already occupied.
