Info on Spay/Neuter and TNR (TRAP–NEUTER-RETURN) 

Why spay and neuter?  Do it for the health of your cat or dog.  Do it to control overpopulation.

Spay/Neuter For Health Reasons:

Spayed cats are less likely to develop breast cancer and will not be at risk for ovarian or uterine cancer, while neutered males will not get testicular cancer. By neutering male cats, you also reduce the risk of injury and infection, since intact males have a natural instinct to fight with other cats. Spaying also means female cats do not go into heat. That means they attract fewer tom cats to the area, reducing fighting.

The average life span of a feral cat outdoors is approximately 18 months.

If cats are sterilized and live in a colony that has a caretaker, they may live more than 10 years.

**The information above is from the ASPCA website… read more FAQ’s here:

Neutered male dogs live 18% longer than un-neutered male dogs and spayed female dogs live 23% longer than unspayed female dogs, according to the report.

Spay/ Neuter For Population Control:

Take a look at the pyramid charts below!

An unaltered cat and their offspring can produce over 400,000 cats in 7 years.

Here’s how:

Beginning as early as five months of age, each cat and kitten can go into heat every 14-21 days.  Once pregnant, the gestation period is 56-65 days.  They can have 2 – 4 litters per year.  You can see that the numbers of potential kittens born grows exponentially.

What is TNR?

Trap-Neuter-Return, commonly referred to as “TNR,” is the only method proven to be humane and effective at controlling feral cat population growth. Using this technique, all the feral cats in a colony are trapped, neutered and then returned to their territory where caretakers provide them with regular food and shelter. Young kittens who can still be socialized, as well as friendly adults, are placed in foster care and eventually adopted out to good homes.

It’s just one 3.5 hour class.  The classes are offered in every borough.  You will learn how to care for the feral and stray cats in your community and make use of the many resources now available to assist you.  All workshop attendees will become TNR certified and NYC residents will gain access to low cost spay/neuter (currently $5 per cat at the ASPCA’s clinic), free traps and equipment, and expert guidance and assistance.
