Is spaying / neutering your pet consider cruel?

What is written in this blog serves no right or wrong from my point of view but how do you see this?

Recently there has been news articles on spaying or neutering pets in Singapore and how owners feel about the whole issue. Some say it is cruel to do that to you pets, while others say it is cruel not to.

Let's look at the What Do "Spay" and "Neuter" Really Mean?

Female dogs and cats are spayed by removing their reproductive organs, and male dogs and cats are neutered by removing their testicles. In both cases the operation is performed while the pet is under anesthesia. Depending on your pet's age, size, and health, he or she will stay at your veterinarian's office for a few hours or a few days. Depending upon the procedure, your pet may need stitches removed after a few days. Your veterinarian can fully explain spay and neuter procedures to you and discuss with you the best age at which to sterilize your pet.

The above prone outcry from owners as they feel what right do human have to remove organs from animals.

However, owners who agree to sterilize their pets feel that they are saving their pets from e.g mammary cancer in female dog. (see below)

Why is spaying / neutering good for your pets?

1) Spaying and neutering helps dogs and cats live longer, healthier lives.
2) Spaying and neutering can eliminate or reduce the incidence of a number of health problems that can be very difficult or expensive to treat.
3) Spaying eliminates the possibility of uterine or ovarian cancer and greatly reduces the incidence of breast cancer, particularly when your pet is spayed before her first estrous cycle.
4) Neutering eliminates testicular cancer and decreases the incidence of prostate disease.

However, there are countries where spay and neutering pets is not the norm, vets do not automatically recommend spay/neuter unless the (eg. dog) has some kind of problem that can be correct through surgery, and most reputable breeders would prefer if their puppies were not spayed/neutered by their new owners. However they do not have hordes of unwanted puppies, because pets' owners know how to handle intact dogs. Dogs are not dropping like flies because of cancer and the vast majority of them lead long happy lives.

Whatever, your views may be, always be a responsible pet owners.
