As for the allergies, yes, a lot of people are allergic to us. The humans now believe that what causes the allergies are secretions from our scent glands. We have scent glands in our faces and the base of our tails. When we rub against people or objects, we are spreading our smell around. This is how we mark our belongings.
Some cats have more secretions than others.
Male cats who have not been neutered tend to have the most. Female cats who have not been spayed have the second most. The second solution is, brace yourself, baths. If you will consent to be bathed once a week with a mild shampoo, your human will be able to tolerate you a lot better. If your human is gentle and comforting, she will probably be able to teach you to tolerate baths.
