Since a ½ oz bottle of Critter Oil® will replace hundreds of dollars worth of premixed products for a single pet household, if you have dogs, cats, horses, birds, a garden, etc.; the 4 oz bottle will handle everything you can imagine for all of your companions, your home, your garden, your lawn, and even your evenings on the patio; just think of how much money you will save over buying premixed products! Remember, the more different ways you use Critter Oil®, the better it will work for you and the more you will love it. The tri-fold instruction flyer included in the packaging has lots of uses and directions, so refer to them often.
