spayed with chemicals?
Chemical spaying and neutering is shown to be equally effective as conventional at precluding fertility and associated behaviors. However, it doesnt effect other attributes such as activity levels, personality and appearance. Chemical spaying, depending on the drug used can be permanent or only last a few years before it has to be done again. These drugs are not currently approved in USA for domestic animals, but they are for zoo animals. However, many European countries, Australia and New Zealand have approved chemical spaying for pet dogs and cats.
These are Gonazon, Suprelorin, Neutersol, Esterilsol, and Infertile.
Suprelorin (deslorelin) one of the temporary drugs is still awaiting approval for domestic pets in USA.

Spaying Good Enough Predator Control
Feral cat populations act as natural predators to help keep wildlife from overpopulating.
Despite popular belief, birds make up only less than one third of feral cats diet, with human garbage making up the majority followed by, rodents and bugs. Feral cats do a good job of procreating regardless of trapping, so thats good news for ferals and birds. The practice of euthanizing cats is therefore unnecessary.
Feral cats have a much better survival rate and health in urban areas than previously thought. That is due largely to their avoidance of natural areas where coyotes spend most of their time. Spayed and neutered animals have even longer longevity.
Spaying and Health Problems
In a nut shell, its best if you can avoid spayign and neutering if you can keep animals contained.
Administering vaccinations while under anesthesia from spaying and neutering is common for pets and livestock alike. Its convenient, but the animals pay the price.The immune system and all its defenses are asleep as part of anesthesia.
Early Spay: No Way!
because it has become common knoledge that it takes intact sex hormones to grow naturally, with skeleton and ligaments and tendons all in harmony.
“Crooked and Crazy” study showed the disastrous effects early neuter had on development, when it occurred in either of the ages studied: 7 weeks or 7 months, vs intact. Bone conformation was distorted (radius to ulnar length), genitals and urinary tracts failed to develop properly, and both groups of neutered animals were “more active”, with the 7 week neuter group judged more “excitable” than the intact group.
a study concluded “Among the findings, neutered dogs were more aggressive, fearful, excitable, and less trainable than intact dogs.”
An earlier study on osteosarcoma showed twice the incidence of this deadly bone cancer in neutered vs intact dogs.
Neutered animals fared significantly worse in all five diseases.
Early neuter of males doubled the rate of hip dysplasia compared to intact males.
None of the intact animals had cruciate ligament disease. Zero. It only appeared in the neutered animals.
Early neutered males had three times more LSA than the intact males, while late neutered males had no LSA.
The percentage of HSA was four times higher in late neutered females than in either intact or early neutered females.
MCT was absent in intact females but present in neutered females. In males, neutering status made no difference.
A study of dogs spanning nearly 40 years and over a million dogs (!) confirmed that female hormones are protective against lymphoma, a cancer that takes over the immune system. Their working hypothesis came from the observation that women don’t get this disease until after menopause. And yes, that’s the state we induce immediately after spaying. Bye bye, female hormones.
Here’s a study from 1994 of 66 dogs studied over five years, and the researchers found neutering was the “most significant … risk factor” in the dogs becoming hypothyroid. Vaccines are another, per Dr. Jean Dodds.
We’ve known for many years that spayed female dogs develop urinary incontinence later in life. Until it was taken off the market for safety reasons, the standard treatment was giving estrogen replacement. Remember, ovaries are the main estrogen producers.
Spaying is credited with reducing risk of breast cancer and pyometra, but wild cousins dont suffer from these largely due to absence of : being multiply vaccinated, for years if not for life. Those pets were likely fed kibble, a very species inappropriate diet, full of toxic byproducts, preservatives, and starches. Most likely they also have been treated with the ever present flea pesticides. Add in the risky heartworm drugs given monthly, and you can imagine being intact was perhaps one small reason for their disease.
at least one study shows that intact animals live LONGER. Spaying and neutering not only potentially shortens the lifespan but also has been correlated with various illnesses. Obesity (sometimes not even responsive to extreme calorie restriction), osteoarthritis, Anterior Cruciate Rupture, diabetes, hypothyroidism, prostatic cancer, hemangiosarcoma, osteosarcoma, urinary incontinence, urinary tract infection, juvenile vulva are just a few conditions that are overly represented in spayed and neutered pets.
The best compromise, if any of these things is too much to deal with, would be to spay and neuter at a minimum of one year if not two years of age. Allow your pet to reach full maturation and reach adulthood before considering surgery.
