Cats can make your throat feel scratchy and sore. In order to help decrease this and other symptoms, you should make sure to vacuum your house regularly (sorry, we hate vacuuming, too). If it's an option, going the hardwood floor route is a way to make this a little easier, since carpet traps allergens. Replace air filters on a routine basis, preferably with HEPA (high-efficiency particulate air) filters.
Pets should also never be allowed in the bedrooms of allergy sufferers, considering how much time people spend in them. Keeping cats off the furniture -- if you're able to accomplish such a challenging feat -- is a good move, too. Try to encourage this by offering them lots of cat-only places to cozy up. It can take a while for allergen-reduction measures to kick in, but with a little diligence, you should start to see some improvement in your symptoms.
