Hair Color And Length Have No Influence On Allergen Production

Hair Color And Length Have No Influence On Allergen Production

A myth exists that suggests cats with darker colored hair and those with longer hair are more likely to trigger allergies than cats with lighter colored or shorter hair. However, hair color and length have no influence on allergen production in cats.

The facts
  • Studies have demonstrated that neither hair length1-4 nor color1,5 influences Fel d1 production or the levels of Fel d1 in the home.
