They are taken to a veterinarian who removes their sexual organs in an operation.
You should make your question a little more clear i suggest something like: What percentage of owners spayed or neutered their pets in the (U.S, Canada, Europe, ect.)
That depends on the pet. Ask the vet.
There is no exact number, but millions of pets are estimated to be spayed or neutered each year in the United States alone to help control pet overpopulation and promote their health and well-being. This number includes both cats and dogs.
That depends on their metabolisms, as well as how much they eat and exercise.
NO! When pets aren't spayed or neutered, they have more serious behavior and health problems. You have to spay or neuter BOTH pets.
The animals which need to be spayed and neutered are cats, rabbits and dogs. Generally the pets which one doesn't want to have a litter of pups or kittens or buns. Also, it is useful for aggressive pets who want to mate but don't have a companion.
Sometimes, and if it happens, call the vet.
Kitten pets can be found wherever owners of female cats fail to get their pets neutered, and will often be freely given to a good home. Animal shelters also have lots of kittens in need of a good home.
No. This is why your pets should all be spayed (if they are female) or neutered (if male). There is no reason to let your pet reproduce when there are already millions of homeless and abused pets who need good homes!
How you live your own life in your own home is nobody's business, unless you commit a crime. Tell them that.
The world is not necessarily overpopulated with cats but there are a lot of dogs and cats out there. That is why people always advise to have pets spayed and neutered.
It all depends on what kind of pet it is and what you plan on doing with it. I would say that dogs and cats should be neutered because there is an overpopulation. However, if you are planning on breeding any types of animals they should not be neutered. This is just my opinion an I may be wrong.
