You should tell your friend with the cat that she should put it away in a bedroom or somewhere else when your visiting.

The best thing you can do is not offend the owner of the cat. It is rude to assume that they should put the cat away somewhere while you are visiting. The cat lives there after all and you don't. Not to mention that the cat simply being in the other room won't help. Additional cleaning does not always help because you are actually allergic to the cat's dander and not the hair. This is very hard to get out but, of course, additional cleaning never hurts. Ultimately, you are the one who can take action. Taking an antihistamine before going over to this person's house will help. It will reduce your reaction and make you more comfortable in their residence. Just remember that people's pets can often be a tricky situation. They can be thought of as family members so when you tell them you are allergic to the cat and could they do something about it, you could offend them. If you find that the medicine works, then its probably not necessary to tell then you are allergic. If it doesn't work then explain it to them nicely and tell them your actions taken to reduce your reaction. If this is the case, they will probably be grateful that you tried and will understand in the future. Lastly, always consult your doctor or allergist. There might be more they can suggest that will help you, and you might want to consult them before picking out a medicine. Hope this helps!

I'd say take an allergy pill. I'm really allergic and there are some pretty harmless, over-the-counter allergy pills. After all, it's just your body reacting to something that it perceives as harmful (sometimes due to genetic patterns from way back). Cats that are given baths give you less allergy. That's because it's the cat's saliva that causes the fur to be so allergenic. But cats hate baths and like licking themselves, so...

My sister is highly allergic to cats! I buy these wipes at a pet store that are specifically designed for reducing allergic reaction. They are quick and easy to use. My sister has no problem now when she comes over! In fact, she got herself a cat and uses the wipes and has no trouble. Animal dander isn't good for anyone, let alone an allergic person. I am not allergic to cats, but since using these I have noticed less dust when I clean each week and easier breathing! If this is a friend you visit often maybe you could buy them a pack or ask them to! You asked what they are called, the ones that my sister and I use are called "Simple Solution" Allergy Relief From Cats. You can find them at Petsmart or petsmart.com. Hope it helps!

There are mediacations out there that people can take for being allergic to cats. My dad is allergic but we have 6 cats.

Something that none of the previous answers have covered is to try to sit in a hard chair. Sofas and comfy chairs are more likely to have embedded cat danders. Whereas dining room type chairs are less likely to be so affected -- you could dust it off prior to sitting on it, if it has cat hair on it.

Some people are allergic to the fur but most people who suffer from allergies can be allergic to the cats lick. avoid your cat licking you, and make sure everytime you handle or play with him make sure you wash your hands before you toach your face, also vacum where the cat has been so fur isnt left around the house.

There is said to be animals that doesn't trigger allergic reactions, but i don't know for sure, since i've been mostly hearing it only.

This may not answer the original question totally, but there is a solution that you can get from a veterinarian that you put on the cat's food twice a day. This solution is harmless to the cat, but it causes some slight changes in the cat's "chemistry" and causes them to be more (though not completely) hypoallergenic. Several of the clients at the vet's office where I work who are mildly to moderately allergic to cats use this for their cats, and they have far fewer problems--enough that they can keep their cats! This doesn't really help if the cat belongs to someone else, but if it's someone whose house you're at often (your sibling, your best friend, etc.) you may see if they will ask their vet about this product.

Daytime Benadryl or Claritin are great...I give to my visitors who have a reaction. I'm allergic to cats too but work around it by wiping down the couches (Allercare products), vaccuuming regularly with fresh hypoallergenic bags, washing the bedding regularly, wiping down fur with a washcloth using only warm water right before my guest arrives. All these things help make everyone comfortable :-)

So you use the wipes to - wipe what? The cat?

Make sure you take your allergy medicine at least an hour, and preferably start the day before you visit the home. When you are there, wash your hands before touching your face or eating/drinking anything. If it's a home you visit regularly, ask if they can pet their cat once a week with Simple Solution Allergy, which you can get at PetSmart.

Take a mild decongestant. I prefer the type at the health food store (less chemicals). You'd be surprised how well they work.
