Within each home range is territory defended against any threats or intruder bobcats. This area is scent marked which appears to reduce actual contact and subsequently making fighting unusual. Breeding usually occurs in winter. The gestation period is 50 to 70 days with young probably born in spring. The litter size ranges from one to seven kittens who feed on mothers milk for about 60 days.
Females reach sexual maturity at one year, males at two.
Natural predators to the bobcat are great horned owls which may take young and adults occasionally are taken by mountain lions and domestic dogs. Competition may also exist between bobcats and coyotes and when coyote numbers are reduced by predator control, bobcat numbers may increase.
