Even one litter contributes to the problem of pet overpopulation. Even if you are able to find good homes for all the kittens or puppies in your pet’s litter, who is to say that every one of the new pet owners will care for them responsibly? Once they leave your home, you have no control over what happens to them. They may end up homeless, abused, or in a kill shelter. Most of the animals who enter shelters end up being euthanized instead of adopted. Are you willing to run the risk of adding to the tragedy of pet overpopulation?
