The Adoption Process

Open Door Animal Sanctuary has the largest selection of adoptable cats and dogs in the St. Louis Metro area. We have more than 250 cats and nearly 100 dogs at our Sanctuary in House Springs every day and also have cats for adoption at the Chesterfield PetSmart year round and dogs several Saturdays a month. 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 will send you home with a healthy pet and the 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.


When you come to Open Door to find a cat or dog to adopt, you will be asked to complete a questionnaire. We reserve the right to decline any applicant who does not meet our adoption requirements. Once you meet and fall in love with your new pet, we will schedule a visit to your home before finalizing the adoption.  Once this is done, you can return to the shelter to complete the adoption paperwork, pay the adoption fee, and take your new pet home!


Our shelter at 6065 Duda Road is open for adoptions by scheduling an appointment due to the pandemic. It is preferred that potential adopters fill out and submit the pre-adoption questionnaire online (  Once received, our kennel or cattery staff will call/email you to schedule an appointment. You can also call the office to schedule an appointment time if you wish at 636-671-3643.  Our Chesterfield PetSmart cats can be seen during their normal business hours.


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. . .
