Species of the palm beaver subfamily eat mainly a wide variety of wild fruits, but also some rodents, birds, snails and scorpions, which provide them with the necessary protein, while various wild fruits provide them with a large amount of carbohydrates. In the Indonesian island of Java, ordinary palm beavers eat all kinds of wild fruits, some wild fruits that are inedible to humans, and ordinary palm beavers eat but are fine. For example, the fruit of mountain palm has many thorns on the outer skin, and even if the ordinary palm beaver eats a large amount into the stomach, it will not harm its digestive system. The premolars of the small-toothed coconut cat are relatively small, and the crown of the teeth is flattened, which is suitable for eating softer fruits. Almost all species of the palm beaver subfamily are well-known "banana eaters", and the common palm beaver is also a "famous" "palm wine stealer". In many parts of southern Asia, bamboo tubes are inserted into palm trunks, and palm juice will seep out along the bamboo tubes, and then automatically collected in a vessel, and people ferment these palm juices to make a very delicious palm wine. Ordinary palm beavers also like to drink these collected palm juices, and they often secretly drink the palm juice that oozes out next to those bamboo tubes.
Almost all of them are carnivorous animals, but wild fruits and insects also make up a certain proportion of their food. The main food of the small spot living in Africa is small mammals such as rodents, while the favorite food of the small spotted deer living in Spain is also a variety of lizards. Through the analysis of the feces of the small spotted otters living in Spain, it is known that half of its food is finches in the spring and summer, and in autumn and winter, various wild fruits account for a significant proportion of their food. The most dominant of the rodents is the chickadee, which is an important food for them throughout the year; although insects make up a small proportion of their food, they are also a regular food from spring to autumn. Some species of the species lurk near puddles formed by rain, catching some frogs for food.
It has been observed that leopard-spotted munds (Chinese commonly known as forest badgers) often eat bats, and when bats fly away from their habitat, leopard-spotted badgers often grab bats to eat.
In the group of palm beavers, there is always a dominant male who controls a large "territory". Over a range of several kilometers, the dominant male would tour the territory every 5 to 10 days, marking the trunks and stems of vines. Secondary males (usually smaller, juvenile or too old males) have much smaller territories and try to avoid encounters with dominant males, so they can only cross the territory for irregular inspections. But when a juvenile, secondary male grows into adulthood, he challenges the dominant male, especially his right to mate with the female first. As a result, war ensues, often with fatal trauma, with the conquered retreating elsewhere and the severely bitten retreating to the ground (usually palm beavers inhabiting trees), either dying of illness or being eaten by leopards or other predators.
The dominant male palm beaver usually contains 1 to 3 females in the territory, and for most of the year, the females do not stay on the same tree as the male, but during the long rainy season, through the night roar, the female and the male can maintain contact. The mating period of palm beavers is in June, which generally lasts for several days, when pairs of palm beavers perch on the same tree. In general, palm beavers have a gestation period of 3 months, 1 to 3 calves per litter, and are produced on a relatively isolated and densely wound vine. The baby palm beaver is weaned 6 months after birth and sexually matures in the second year. In general, male palm beavers leave their place of birth to find their territory after weaning, while female palm beavers can live with the mother palm beaver for nearly two years before dispersing.
African civets almost always excrete feces in piles on the routes they often walk, and a pile of civet cat feces can cover an area of nearly 0.5 square meters, which indicates that African civet cats occupy territory, and the dung piles are usually on the boundaries of the territory, which can play a role in communicating with neighbors. African civets also often mark the scent of cats secreted by the perineal glands on fruit trees and bushes that bear wild fruit, and occasionally on grasses, branches or rocks. Female African civets mature sexually at the age of 1, after which they can give birth to 2 litters in a year, each pregnancy period is 80 days, each litter is 1 to 3 calves, usually on relatively isolated thick vines. The cubs need to be fully cared for by the mother African civet cat for 3 to 5 months, and they must learn the ability to catch insects before weaning. During the care of the cubs, if the female African civet catches a rat or bird, it will make a "whooshing" sound to summon its cubs to share.
