The Most Effective Cat Birth Control Methods

You should be concerned about your cat being pregnant. Even if your cat only breeds once in a while, she can generate hundreds of kittens in her lifetime. Her kittens are also capable of reproducing, and so forth. In just a few years, a single cat can have thousands of offspring.

Should You Spay or Neuter Your Cat?

Most of you are aware that your cat may be spayed at your local veterinarian office. The surgery is not expensive, there are few drawbacks and many benefits, and the most common procedure we perform is an ovariohysterectomy, which removes the uterus as well as the ovaries so your cat no longer risks health problems during pregnancy, no longer howls during heat, and no longer runs away to be bred.

Not everyone wants a permanent solution, not everyone has a nearby veterinary facility, and not everyone can afford to have their cat operated on. There are other options for cat households that cannot afford or do not want a permanent solution.

Why Should I Put My Cat on Birth Control?

The fact is that most individuals do not want to take one of your kittens home with them. If you have a particularly exceptional and uncommon breed cat, a big number of individuals have previously requested babies, and you are prepared to locate homes or take in kittens that the new owner does not want or takes back, you may be justified in breeding your cat.

Otherwise, leave it to the breeders who are constantly dealing with this issue.

Will you leave it to the breeders yet still require birth control? One key argument for putting a cat on birth control rather than spaying her is because certain locations just do not have the resources to do so. A cat must be put under general anesthesia and have her abdomen surgically penetrated in order to have an ovariohysterectomy. This is quite common at most clinics across the world, but it is a concern in some regions. Birth control hormones may be widely accessible and inexpensive in other areas of the world, but surgery is not an option.

When surgery is not an option, hormones are accessible and simple to use.

Best Temporary Birth Control Methods for Cats

Megestrol acetate tablets are not as popular as hormone injections, but they may be a suitable option for individuals who are unable to spay their cats. It is administered in the form of tablets or drops in food; cats receive roughly 2.5 mg once a week, but if they are already in heat the first time, they require a higher dose for three days. When cats are fed together, one cat may receive the dose intended for another, causing issues for both cats.

Megestrol acetate was once used as a birth control for dogs, but it is no longer used since it causes breast cancer. According to one prominent website for a wild cat charity, it is safe and secure.

It has not been used in enough cats for all of the negative effects to be observed and documented, and because it is not authorized and there are other options for feral cats (such as trap/neuter/release programs), it is unlikely to be popular enough to merit further research. Although it is an option for individuals who feed wild cat colonies and are unable to catch their cats, I believe hormone injections are a better choice for those who are unable to spay or neuter their cats.

Because side effects cannot be purchased, they must be created at a compounding pharmacy.

Hormone Injection

The most frequent form of birth control injectable used in cats is medroxyprogesterone acetate, a progestin-like substance. In the United States, it is a prescription medicine offered under the brand name Depo Provera. It is sold over the counter in some countries and may be found in some feed stores.

Hair loss, increased water intake, and diabetes have all been mentioned as side effects. If the injection is administered at the incorrect time, the cat may develop an infection in her uterus.

Cats only require the injection every 4 months, either 3 weeks or more after being in heat or 3 weeks after kittens are born. The dosage is 2-4 mg/kg, and tiny vials are sold at pet and feed stores in several countries.


Cons: reasonably easy to obtain and utilize; effective for 4 months

Some potentially dangerous side effects might be difficult to administer, especially if administered at the incorrect time.

Hormone Chip

One disadvantage of administering an injection is that the cat must be brought to the vet every three or four months. This is not an issue with the hormone chip because it lasts so long. A 4.7 mg GnRH (deslorelin) chip is implanted beneath the skin, and studies have shown that it is effective for around 24 months.

When the chip wears off, the cats become fertile again and may be successfully bred.

There have been no severe health issues revealed as of yet. However, in some cats, the chips can actually encourage them to go into heat immediately after implantation. In others, heat can occur as soon as 15 months after the implant is placed, and owners can never be certain when the cat will begin to come into heat again.
Where accessible, hormone chips are a viable alternative since they do not have the side effects of tablets or injections and are reversible.
