There's nothing wrong with a fish, or a snake, or a hermit crab or turtle, but they don't love you back. If you're allergic, it's a serious trade-off. Fifteen to thirty percent of people with allergies have allergic reactions to cats and dogs.
Cat allergies are about twice as common as dog allergies.
People tend to think it's the fur that's the problem, but it's not. Many airborne particles are small enough to get into the lungs. When they are inhaled, the allergens combine with antibodies. This can cause severe breathing problems. So, it's best to remove the furry creatures and settle for the scaly ones.
