Spay & Neuter, TNR

If you adopt a cat, dog or rabbit from BCAS, the animal will already be spayed or neutered.  Spaying refers to the removal of the reproductive organs of female dogs and cats, while neutering is the removal of the testicles in male dogs and cats. Spaying or neutering your pet is essential for many reasons.  In addition to the health and behavioral benefits, it will help control the overpopulation of animals, which results in many dogs and cats living in shelters or rescues being euthanized each year.

Medical benefits to spaying or neutering your pets include:

  • Spaying (for females) helps prevent uterine infections (pyometra) and cancers and breast cancer, which can be malignant in about 50 percent of dogs and 90 percent of cats according to the ASPCA. Spaying your pet before her first heat offers the best protection from these diseases.
  • Female animals with diabetes or epilepsy that are spayed have fewer hormonal imbalances which helps to control these diseases.
  • Neutering your male pet prevents testicular cancer and some prostate problems.
  • Spaying or neutering will NOT make your pet fat. Lack of exercise and overfeeding will cause your pet to pack on the extra pounds-not neutering. Your pet will remain fit as long as you continue to provide exercise and monitor food intake.

Behavioral benefits include:

  • Your spayed female pet won't go into heat. While cycles can vary, female cats and kittens usually go into heat four to five days every three weeks during breeding season, and can start their first cycle as young as 4 months. In an effort to advertise for mates, they will yowl and urinate more frequently, which can be a persistent behavior that is often troublesome to pets and owners.
  • Your male dog or cat will be less likely to roam away from home when they reach puberty. An intact male will do just about anything to find a mate, including finding creative ways escape from the house. Once he is free to roam, he risks injury in traffic and fights with other male animals.
  • Your neutered male may be better behaved as intact male dogs and cats display more aggressive behaviors. Unneutered cats are more likely to mark their territory by spraying strong-smelling urine. An unneutered dog might be less likely to mount other dogs, people and inanimate objects after he is neutered.
  • Unneutered male cats, especially those outdoors, are more prone to fighting for territory, which can spread FIV and FeLV, or cause injuries with severe infections and abscesses.

Low Cost Spay and Neuter

The shelter does not provide spay/neuter services for owned animals.  For information on low cost spay/neuter of owned animals, you can contact:

Trap/Neuter/Return (TNR)

The Trap/Neuter/Return (TNR) Program overseen by the Bergen County Department of Health Services is available to towns that contract with our Animal Control services and who permit the care and feeding of outside colonies under their town ordinances. 

The Shelter is committed to providing TNR services to those cats by having them spayed or neutered and vaccinated.  The goal is to reduce the population by stopping reproduction, care for and treat the cats in a humane manner, and to prevent the spread of disease to the public by vaccinating for rabies. 

Guidelines for the program include:

  • Cats that are captured in humane traps will be brought to the Shelter Monday through Thursday between 8:30am and 9:00am. Cats will not be accepted after 9:00am.
  • The Shelter will accept a maximum of 10 cats on a given day
  • Due to holiday and veterinary availability, the Shelter has the right to cancel a drop off on any given day. Attempts to notify trappers through social media outlets will be made
  • Trappers will be required to provide a driver’s license as identification, designate the location the cat was trapped and the location to which the cat will be returned
  • The Shelter will NOT accept kittens approximately 12 weeks and under for the TNR program. If kittens are trapped and brought in, they will be surrendered to the Shelter, for foster and/or adoption
  • All cats under this program will be ear tipped
  • The trapper will be given a receipt with a list and description of the cat(s) left for TNR that day. It will be the responsibility of the trapper to pick up the cat(s) at the designated veterinary location later that day, usually between 3:00pm and 5:00pm
  • Services other than spay/neuter and vaccines (rabies and distemper) are available for a cost to the trapper and must be requested at time of drop off. These fees are paid directly to the veterinary provider.
  • The veterinary clinic has the right to refuse to perform surgery on any given cat that is deemed medically untreatable and that is inhumane to be returned to the colony location.
