Order: Carnivora | Family: Canidae
Biology: Foxes live either solitarily or in family groups. They dig dens with at least two exits, which may be used for several years. Mating occurs from late January through the first ten days of February. Females breed once a year, typically giving birth to 6–8 kits. They reach sexual maturity at 10 months.
Habitat: Forest, steppe, and meadow ecosystems, as well as rocky areas and agricultural lands.
Ecological Role: They are omnivores that feed primarily on rodents, which make up about 70% of their diet; however, they also consume birds, hares, and occasionally fish, reptiles, insects, and plants. Their average lifespan in the wild is 5–6 years.
Conservation Status: In the IUCN Red List – LC.
Order: Carnivora | Family: Canidae
Biology: Jackals live either solitarily or in family groups. They dig dens with at least two exits, which may be reused over several years. Mating occurs between late January and early February. Females breed once a year, typically giving birth to 6–8 pups. They reach sexual maturity at 10 months.
Habitat: Forest, steppe, and meadow ecosystems, as well as rocky areas and agricultural landscapes.
Ecological Role: As omnivores, their diet consists primarily of rodents, which make up about 70% of their food intake. They also eat birds, rabbits, and occasionally fish, reptiles, insects, and plant matter. The average lifespan in the wild is 5–6 years.
Conservation Status: In the IUCN Red List – LC.
Order: Carnivora | Family: Felidae
Biology: A small feline, with a body length of 75–90 cm and weighing 3–8 kg. It is a solitary animal with highly developed hearing and vision, and is primarily nocturnal. Mating occurs in February or March, and after a gestation period of about 70 days, the female gives birth to 3–6 kittens. The kittens are capable of following their mother on hunts after one month, and by approximately three months, they can hunt independently.
Habitat: Prefers forests with many old trees and secluded thickets, as well as tree and shrub areas within agricultural landscapes.
Ecological Role: A predator that hunts by lying in ambush for long periods before launching an explosive leap. It feeds mainly on rodents, rabbits, lizards, frogs, birds, and fish, and occasionally attacks roe deer fawns. Their lifespan in the wild is 10–12 years.
Conservation Status: Listed in the Red Book of the Republic of Moldova [VU] and in the IUCN Red List – LC.
Order: Carnivora | Family: Mustelidae
Biology: A medium-sized mammal, weighing between 7–13 kg in summer and 15–17 kg in autumn. This is a social, monogamous, and territorial species that is active at night. Mating occurs from July to August; after a gestation period of 270–280 days, the female gives birth to 3–4 cubs between January and April. Cubs become independent at six months of age. Badgers are known for building complex dens with tunnels reaching up to 80 m in length and for hibernating during winter, for which they accumulate fat reserves comprising up to one-third of their body weight.
Habitat: Forest ecosystems.
Ecological Role: An omnivorous species that feeds on insects, snails, earthworms, rodents, and small mammals—including rabbits and hedgehogs—as well as plant matter such as corn, wheat, oats, grapes, fruits, and mushrooms. Their lifespan in the wild can reach up to 15 years.
Conservation Status: In the IUCN Red List (LC).
Order: Carnivora | Family: Mustelidae
Biology: An amphibious mammal measuring 50–82 cm in body length and weighing 5–14 kg; males are significantly larger than females. Adapted for a semi-aquatic lifestyle, they possess an elongated body, a flattened tail, and webbed feet. The reproductive cycle is continuous, with mating occurring in February–March and July. After a gestation period of 60–70 days, the female gives birth to 2–3 pups, which stay with their mother for up to 14 months. They reach sexual maturity at 2–3 years of age.
Habitat: Occupies all types of aquatic ecosystems, nesting on land near the water's edge.
Ecological Role: An active predator, consuming approximately 1 kg of food daily, including fish, crustaceans, mollusks, amphibians, small mammals, birds, eggs, insects, and occasionally plant matter. Their lifespan is 5–10 years.
Conservation Status: Listed in the Red Book of the Republic of Moldova. In the IUCN Red List – NT at the global level.
Order: Carnivora | Family: Mustelidae
Biology: A small mammal, measuring 38–55 cm in body length and weighing 0.9–1.6 kg. It is a solitary animal and an exceptional climber, well-adapted to hunting within the forest canopy. They reach sexual maturity at 14 months. The gestation period is lengthy, with a litter of 3–5 kits typically born in April, which then become independent after 3–4 months. They possess highly developed senses of sight, hearing, and smell.
Habitat: Deciduous and mixed woodland regions, including the forests of the Central Codri, the Dniester and Prut floodplains, island forests, and, increasingly, wooded areas within human settlements. They roost in tree hollows.
Ecological Role: A nocturnal predator with a varied diet consisting of rodents, birds, insects, frogs, reptiles, berries, and occasionally snails, fish, or rabbits. In turn, they are preyed upon by foxes, jackals, wolves, owls, and eagles. Their lifespan in the wild is approximately 10 years.
Conservation Status: Listed in the Red Book of the Republic of Moldova [VU] and in the IUCN Red List – EN in Europe.
Order: Carnivora | Family: Mustelidae
Biology: The smallest carnivorous mammal, featuring a slender body measuring 13–26 cm in length and weighing between 30 and 250 g. It is a solitary, highly agile, and aggressive predator, primarily active at night. They reach sexual maturity at one year of age. The mating period begins in March–April; after a gestation period of 34–37 days, the female gives birth to 4–7 kits, which she raises exclusively. The young become independent at 3–4 months.
Habitat: Forests, shelterbelts, agricultural lands, floodplains, marshes, rocky areas, and human-modified environments (such as woodpiles and barns). They often use the burrows of the rodents they hunt.
Ecological Role: Their diet consists mainly of rodents (mice, hamsters, ground squirrels), though they also attack rabbits, birds, frogs, and reptiles. The average lifespan in the wild is 5–6 years.
Conservation Status: In the IUCN Red List – LC.
