Among the snake predators, Taiwan tree snake, Taiwan kukri snake and Pointed- scaled pitviper were responsible for most predation events.

与地面巢(71.4%)的共同主要掠食者，又以大头蛇、赤背松柏根与龟壳花最为常见；灌丛巢的次要掠食者为鸟类与台湾猕猴，地面巢则是须面对食蟹獴与白鼻心等在地面活动的哺乳类天敌。

The time and frequency of the polecat searching different preys and burrows were nearly the same. The polecat attacked virtually all prey offered and thus exhibited opportunistic foraging behaviour. However, it did not captured all prey with equal sequence. It first captured the zokor, then the pika and last for the root vole. In addition to using the typical musteline killing method of biting the nape of the neck, the polecat evolved a variety of killing methods suited to a range of prey types depending on the activity, size and anti-predation ability of prey. The zokor was bitten on the head, whereas the pika was killed by bites to the head or throat and the root vole was killed by bites to the head or chest. The time polecats pursued the root vole was the longest, followed by that used in pursuing the pika and the zokor.

实验结果表明：艾虎对三种猎物的搜寻时间和搜寻频次基本一致，在搜寻猎物的过程中并非已知洞道系统中所存在的食物信息，是一种机会主义的捕食者；艾虎除了具有典型鼬科动物捕杀猎物的方法外，能够根据猎物的大小、活动性和反捕食能力采用不同的捕杀方法，在捕杀猎物的过程中首先捕杀高原鼢鼠，其致死部位全部为头部，其次捕杀高原鼠兔，其致死部位除了头部外，明显增加了颈部的比例，最后捕杀根田鼠，其致死部位主要是头部和胸部；艾虎在捕杀猎物的过程中，追击根田鼠的时间最多，追击鼢鼠的时间最少，而用于捕杀根田鼠的时间最少，用于捕杀鼢鼠的时间最多，艾虎捕杀高原鼠兔后单位时间内获得的能量值最大，其次为捕杀高原鼢鼠，而捕杀根田鼠后单位时间内活动的能量值最小。
