I told him about AllerPet, but does anyone have any other suggestions for
him?

I had a boyfriend who was highly allergic to cats. This worked perfectly with
no medication. It will also get rid of other allergies as well.

No rugs or carpeting, only hardwood floors, tile or linoleum. No drapes, fabric
furniture, only blinds, shutters, leather and wood furniture. Easy to wipe down
often to reduce dander and dust. You do the wiping and vaccuming for her.
You'll save time cleaning also.

You wash the cat once a month to reduce dander. Every day you wipe the cat with
a moist cloth to remove hair and dander. Kitty loves it.

Get an air purifier and keep the windows closed so dust, dander, pollen can't
come inside. Wipe surfaces down frequently for the same reason.

Don't ever let the cat in the bedroom. Don't let the cat sit where he sits all
the time such as the couch or her desk chair. Don't leave her sweater lying
around for them to sit on. Tell her to rinse her hands after touching the cat.

Check your house for other allergens. Is a sink leaking and you have mold and
mildew? I heard of a guy who euthanized his cat as he SWORE it was the cat. He
still had allergies...and extreme guilt. I'm allergic to cats also and this
works for me too. Just keep in mind he'll still have allergies outside of the
house as other people have cats and you can't stop dust and pollen.
