The Adoption Process

Open Door Animal Sanctuary has the largest selection of adoptable cats and dogs in the St. Louis Metro area. Whether you are looking for your first family pet or adding to your existing family, the staff at Open Door can help you find that special someone who is right for your home. The members of our cat-care and dog-care teams are experienced in matching up the right pet with the right situation and making sure your new family member is properly introduced to your current ones.

We send you home with a healthy pet and support you may need to help your new pet adjust to their new home.  All of our animals receive full medical and behavioral evaluations.  We take great pride in providing the finest possible veterinary care to our animals.  Our veterinarians provide a full array of preventative care for the cats and dogs when they first arrive and continue caring for them while they are living at our sanctuary. Our cats and dogs are given vaccinations, including rabies – when over four months old, de-wormed, spayed/neutered and microchipped. Dogs are tested for heartworms and given a heartworm and flea/tick preventative monthly. Cats are tested for feline leukemia/feline aids and given a flea/tick preventative.


Our goal is to find permanent, loving homes for our cats and dogs so that they do not end up back on the streets and ultimately back at our sanctuary.  Before you visit Open Door, please be sure to discuss a new pet with other family members in the home to make sure they are all in agreement. Prior to meeting one of our cats or dogs, potential adoptors will be asked to complete a questionnaire. We reserve the right to decline any applicant who does not meet our adoption requirements. The next step is to fall in love with one of our furry friends! We will then schedule a visit to your home before finalizing the adoption.  Once this is done, your new best friend will be ready to come home.  There will be paperwork to sign and an adoption fee to pay.


Our adoption fee is $75 for adult cats (age one and over) and $150 for all dogs/puppies and kittens.


The adoption fee includes:

  • spay/neuter
  • vaccinations (including rabies for animals over 4 months old)
  • microchip
  • current on heartworm preventative (dogs and puppies)
  • current on flea/tick preventative (all animals)


We will send you home with:

  • your cat or dog’s medical records
  • microchip registration
  • a starter bag of Purina One food
  • a bag of cat or dog goodies (treats, toys & more!)
  • collar, lead and ID tags (for dogs)

Open Door Animal Sanctuary has a lifetime return policy on our cats and dogs which means if you can no longer care for them, they must be returned to us.

We do have one final requirement – you must promise to give your new family member. . .

We try to keep our on-line listing of pets updated but due to time constraints, some cats and dogs may not be shown. If you have a particular type of pet in mind, please give us a call at (636) 671-3643 to see what we currently have available.


Just because it isn’t listed, doesn’t mean that we don’t have the perfect pet for you!
