Why you should spay/neuter your Sphynx feline
Spaying or neutering your Sphynx feline has many advantages. For the female Sphynx, spaying will keep them from coming into the heat cycle. An un spayed female Sphynx will normally come into heat several times a year which can last anywhere from several days to several weeks. Along with the inconvenience of dealing with your female Sphynx’s cycle there is also the potential for bad behavioral issues such as spraying urine, marking with urine, howling and many other types of obnoxious behaviors, things you normally wouldn’t expect from your female sphynx.
On the other side of the coin for the male sphynx if you neuter them before they reach puberty it almost always prevents the development of the mating behaviors that can cause such problems as spraying urine, marking territory with urine and the desire to roam in search of a mate. Eliminating the desire for your male sphynx to roam helps insure he has a long life.
Need more to convince you to spay or neuter your sphynx felines
Although many people have the theory that allowing your sphynx to have at least one litter, consider what would happen if everyone in the world does this. This is where the feline over population comes into play and as a result the need to euthanize so many felines. A large part of the reason why so many people want to allow their sphynx to have at least one litter of kittens is because they believe this gives their children the experience of the miracle of birth, at least in the animal world.
Many think that breeding is the key to a second income, this is not necessarily the case when it comes to breeding felines, whether sphynx or another breed. When an expectant feline is truly cared for properly when she is pregnant, including pre-pregnancy, breeding, pregnancy and post-pregnancy, and the kittens are wormed, vaccinated, advertised and then sold, after you have deducted the vet costs, the food costs and the inevitable damage from the kittens as they learn to potty to your furniture and rugs, you really haven't made much of a profit to speak of.
So the best advice here is to enjoy your feline when they are little. However, make certain you spay or neuter them when they reach the proper age to help prevent feline overpopulation, which in turn eliminates euthanasia.
