How to reduce cat allergies

How to reduce cat allergies? Here are ten tips:

1. Male cats should be neutered. Male and female cats that are neutered/spayed have similar levels of Fel D1 allergen but unneutered males are the worst.
2. Thinking long term, if a child is exposed to a domestic cat he or she has a lesser chance of being allergic to cats when older. There are resistant to it. Conversely adult people who are first time cat caretakers are less resistant (half as resistant) especially people with allergies to other substances¹.
3. Cat avoidance measures should be taken. This is rather self-defeating though. Keeping your cat out of the bedroom at night helps.
4. You can more or less ignore stories of certain cat breeds being hypoallergenic. There are a lot of claims on the internet all of which are scientifically unsubstantiated.
5. Use a HEPA filered air purifier.
6. Use the best type of vacuum cleaner with a HEPA filter.
7. Wash your cat's coat once a week. I think this is not that practical to be honest.
8. Wash your hands after handing your cat. Once again somewhat self-defeating.
9. If you have a large enough home, keep one room for your cat where he can go so that you can gain some respite from the Fel D1 allergen.
10. Continual close exposure to Fel D1 can sensitise the person even though there was no sensitivity previously. Points 8 and 9 help to reduce the speed of this process.
