Last Litter Program for Dogs and Cats

The Last Litter Program is for pet cats who have a litter of kittens or pet dogs who have a litter of puppies whose guardian needs help rehoming and getting their mama cat or dog spayed to prevent future litters.

HSU will intake the kittens or puppies for adoption and vaccinate, spay, and return the mama cat or dog to you on the same day.


The intake fee for a litter of kittens or puppies is $100 to help offset the cost of care provided to the kittens or puppies (including vaccination & deworming, spaying/neutering, and microchipping) until they can be adopted. There is no additional fee to vaccinate, spay and return mama cats or dogs to their homes through donations and grants from our generous supporters.

A $30 deposit is required to hold the appointment, which will go toward the total $100 intake fee.


Available for legally owned pet cats and their kittens under 5 months of age or pet dogs and their puppies 3 months or younger. For stray animals, please contact your local animal services.

  • A litter consists of a Mama cat or dog and at least two babies.
  • Kittens or puppies must be 8-9 weeks old and at least 2 pounds before being separated from their mamas.
  • Mama cat or dog must be in sufficiently good health for spay surgery. Our medical team may reject any animal for surgery if it poses a risk to their health and/or other animals due to potentially contagious diseases.
  • In addition to the health requirements listed above, our staff must be able to safely handle your pets. We may be unable to accept any pets that pose a safety risk to people.
  • After surgery, the mama cat or dog is returned to her guardian, and the Utah Humane Society will adopt the kittens or puppies through our adoption program.
  • The Humane Society of Utah does not guarantee the acceptance of all animals into this program. We hold the right to decline animals that do not meet our intake guidelines.

Free-roaming community cats living in your neighborhood may be served by our CATNIP program to vaccinate, spay/neuter, ear tip, and return them to their communities.
