text: how can my cat and allergic boyfriend coexist?   i had the same problem (now solved). i got the advice from an allergy advice website. ban the cat from the place your bf sleeps (even when he's not there). vacuum floors/carpets every day when your boyfriend is out and open all the windows for at least 20 minutes afterwards. also vacuum sofas and cushions and the cat's bed every day. now for the mad-sounding bit - wash the cat! every day, gently pour a jug of warm water over the cat as he/she sits in the bath/sink, then run your hands over the cat to squeeze out the excess. when dry, groom the cat for 10 minutes. do this daily for one week, then once weekly after that. it sounds a lot of work but it all takes around half an hour a day. it definitely worked for me and my bf. good luck!
