Behavioral problems are also common among animals that remain intact. Aggression can be a serious concern for both male and female animals. Spaying and neutering will not guarantee 100% that an animal will not be aggressive, but it does greatly decrease the chances. Many animals are
euthanized each year solely because of aggression towards other animals
and/or people. Urine spraying is the number one reason most owners have their male cat neutered. Again, neutering does not guarantee 100% that the spraying will stop; however, the cat is much less likely to spray if neutered.
Not only are cats and dogs injured by cars, but people may also be injured in an attempt to avoid hitting them. Both the person and the car could sustain serious and expensive injuries. Spaying and neutering will decrease the number of animals that roam our streets.
Over one million people report dog attacks each year; millions more go unreported. About 12 people annually die from dog bites (more than sharks!). Each year dog attacks cost society $1 billion. Studies have shown that the majority of the dogs doing the biting are intact male dogs. The American Veterinary Medical Association recommends spaying and neutering to decrease aggression
in these dogs.
Roundworms and Hookworms
Roundworms and hookworms are intestinal parasites found in cats and dogs. These parasites are abundant in puppies and kittens. Some worms can be transmitted to puppies and kittens before birth. The worms are shed in the feces of an infected animal. Many stray animals will defecate in parks and playgrounds where children play. Children are more susceptible to contracting these parasites than are adults. In people, the parasite may cause severe skin disease and eye disease including blindness. Controlling the pet overpopulation will help decrease the number of animals that are not properly vaccinated or dewormed.
