I have never had a problem when ordering from you. I try to order a bit earlier than needed. I am very satisfied with your company. We have seven stray cats that we have taken in over the last 15 years. Two of our cats are going on 15 years old. They have all been taken to the veterinarian for shots and spayed or neutered. I have been using the flea and tick medication for over six years since I found out about you. Thank You.
