Final answer:
The statement is false. The length of an animal's hair does not determine how allergenic they will be to someone with pet allergies. The proteins in an animal's skin, saliva, or urine are the main triggers for pet allergy symptoms.
Step-by-step explanation:
The statement in the question is false.
Allergies occur when a person's immune system overreacts to substances in the environment, known as allergens, such as pollen, pet dander, or dust mites. The length of an animal's hair is not directly related to how allergenic they will be to someone who suffers from pet allergies. Instead, the proteins found in an animal's skin, saliva, or urine are the main triggers for pet allergy symptoms.
For example, a person with a cat allergy may experience symptoms when exposed to a long-haired cat or a short-haired cat, as the allergenic proteins are present in both types of cats.
