Thank you for considering adopting a pet from Nassau Humane Society! Here, you will find all of our current available cats and dogs. Our animal profiles are updated in real-time, so all of the animals shown are still available at this time. If you don’t see what you’re looking for, keep checking back as we are rescuing animals on a regular basis or, feel free to visit our shelter to do a walk-through with one of our experienced kennel technicians who can help you find the right fit for you and your family!

Please consider when looking for a new addition to your family, that adopting a pet is a life-long commitment and we are looking for adopters that understand every animal has their very own personality. When a cat or dog is brought into a new environment, they will go through a decompression and adjustment period, so we are asking for your patience when introducing a new pet into your loving home!


  • Applications are available at the shelter and animals are adopted on a first come, first served basis.

  • You will need a valid photo ID.

  • You must be at least 18 years of age or older.

  • Adoption fees and other related fees can be made by either cash, credit card, or debit card. Checks will only be accepted for donations.

  • If you plan to adopt a dog, you must provide your own leash and collar. These items can be purchased at the shelter from our boutique.

  • Cats are required to leave in a cat carrier. We have temporary carriers available for purchase at the shelter if you do not have your own.

  • If you are interested in adopting a dog and have your own dog already, a meet and greet at the shelter may be required to proceed with the adoption process.

  • If you rent your home, please look into your landlords’ pet requirements prior to adoption.

  • While most of our available animals are at our facility, some that you see on the website may be in foster care or at an offsite event.

  • We strongly recommend that all current members in your household meet the animal you are interested in prior to adoption to ensure it is a good fit for everyone.


All of our cats and dogs will be spayed/neutered, microchipped, and up-to-date on all eligible vaccinations, tests, and prevention prior to adoption.

If you fall in love with an animal that is not yet up-to-date on any of the above medical necessities, you will be eligible to put down a hold fee, pending application approval, until they are ready to be taken home.
