First of all when it comes to spaying or neutering cats or dogs it is vitally important to understand the dog and cat health implications of why your pet should be spayed or neutered. If you are an animal breeder you may feel like this information does not apply to you, but it is good that you know about dog and cat health in regard spaying and neutering so that you are able to inform those who acquire their pets from you. One of the biggest regrets about domestic animals is that so many people do not get their pets spayed or neutered and, as nature runs its course, the animals give birth to unwanted litters and as a result of this many animals end up on the street and ultimately in overloaded shelters.
If you have no intention of your breeding your pets then by having female pets spayed you can save your pet undue dog and cat health issues, and physical and mental stress caused by the natural heat cycle that occurs every three weeks and lasts four to five days. In male pets you can also save a lot of undue stress as a neutered male will tend to roam and fight a lot less than an un-neutered male pet, and once neutered male cats also stop marking their territory, i.e. your furniture.
