Some people are allergic to cats no matter how much they may love them. Happily, some people can also develop an immunity to cats even if they’re initially allergic to them. Allergies occur when your body detects substances as foreign and dangerous items to your body. So developing immunity means giving yourself low-level exposure to your cat.
Start by giving yourself a bedroom where you can be completely free of your cat and its dander. Then try using anti-allergy shampoo on your cat while adding Omega-3 fatty acids to your cat’s diet. The goal is to constantly expose yourself to your cat until your allergy finally goes away.
