You should spay/ neuter your pets because that is what a veterinarian recommends. Some excuses you hear are: It is too expensive, it is not natural to have them fixed, my friend did not and their animals are fine. Having your pets spayed/ neutering can be expensive but having offspring can be even more expensive. In the end, it is better for you and your pets.
The expense is a major issue with spaying and neutering pets. People do not understand how much money they would be saving if they would just spay/neuter their pets. On average the cost of a dog or cat spaying is around two hundred dollars. It could be more or less it just depends on the clinic. You would only have to spend that money once and you are done for
