Males of many animal species compete for mates, either by producing showy ornaments to attract females, such as the plumes and bright colours of male Birds of Paradise, or, like stags and elephant seals,
by fighting with other males for access to mates.
Not exact matches
After two
males fight, one may reconcile
with his opponent
by presenting his rump and backing up against the
other's testicles.
However, if a
male persists in attempting to mate
with an unreceptive female, a
fight may break out — and such
fights can end
with one of the shrews being killed and eaten
by the
other (pdf format, see page 11).
By neutering
male cats, you also reduce the risk of injury and infection, since intact
males have a natural instinct to
fight with other cats.
Neutered
male dogs and cats have less urge to roam and, consequently, less risk of exposure to contagious diseases, less contact
with other animals that could result in
fights, and less risk of being hit
by a motor vehicle.
A neutered
male is less likely to roam, get hit
by a car,
fight with other males, get lost, behave aggressively, or climb on unsuspecting visitors in your home.
Roaming predisposes him to getting shot, hit
by car, poisoned, and to
fighting with other intact
males.
In addition, the study showed that intact
males were twice as likely to hit
by a car and get injuries from
fighting with other animals.
