Predation on domestic animals

During the early years of ranching, cougars were considered on par with wolves in destructiveness. According to figures in Texas in 1990, 86 calves (0.0006% of Texas's 13.4 million cattle and calves), 253 mohair goats, 302 mohair kids, 445 sheep (0.02% of Texas's 2 million sheep and lambs) and 562 lambs (0.04% of Texas's 1.2 million lambs) were confirmed to have been killed by cougars that year. In Nevada in 1992, cougars were confirmed to have killed nine calves, one horse, four foals, five goats, 318 sheep, and 400 lambs. In both reports, sheep were the most frequently attacked. Some instances of surplus killing have resulted in the deaths of 20 sheep in one attack. A cougar's killing bite is applied to the back of the neck, head, or throat and the cat inflicts puncture marks with its claws usually seen on the sides and underside of the prey, sometimes also shredding the prey as it holds on. Coyotes also typically bite the throat, but the work of a cougar is generally clean, while bites inflicted by coyotes and dogs leave ragged edges. The size of the tooth puncture marks also helps distinguish kills made by cougars from those made by smaller predators.

Remedial hunting appears to have the paradoxical effect of increased livestock predation and complaints of human-cougar conflicts. In a 2013 study, the most important predictor of cougar problems was the remedial hunting of cougars the previous year. Each additional cougar on the landscape increased predation and human-cougar complaints by 5%, but each animal killed during the previous year increased complaints by 50%. The effect had a dose-response relationship with very heavy (100% removal of adult cougars) remedial hunting, leading to a 150% – 340% increase in livestock and human conflicts. This effect is attributed to the removal of older cougars that have learned to avoid people and their replacement by younger males that react differently to humans. Remedial hunting enables younger males to enter the former territories of the older animals. Predation by cougars on dogs "is widespread, but occurs at low frequencies".
