European rabbits are infamous for their destructive behaviour. They eat shrubs in orchards and forests causing heavy loss of vegetation and biodiversity. Rabbits are also domesticated widely across the world, either for food or as pets. Red foxes dig their burrows in areas like mountain slopes, ditches, depressions, steep water banks, etc. They prefer a well-drained spot to dig a burrow. A red fox's burrow is made up of a main den and temporary dugouts.River otters, being semi-aquatic, prefer their dens to be close to water. They choose dens constructed by other animals or dig in natural hollows to live in. Badgers are nocturnal mammals who dig complex networks of underground tunnels connecting to their respective dens. They have a long black and white snout, and sharp claws required to dig. Their preferred habitats are sandy, loamy soils which ideally have easy access to freshwater and prey. Moles are small mammals with a pointed conical snout, velvety fur, and unnoticeable eyes and ears. Their forelimbs have large paws with pointed fingers which help them dig efficiently. They feed on earthworms and other small, soil-dwelling invertebrates. A mole is known to heap soil and create a hill surrounding the entrance of the den. The common shrew is native to Britain and exists commonly in scrub land, grassland, hedgerows, and woodland. Shrews mostly occupy burrows dug by other animals and surface every 2-3 hours to feed themselves. Shrews feed on insects, spiders, worms, amphibians, and small rodents. Ants are some of the most common burrowing creatures. Although ants dig holes, they create huge mounds of soil right at the entrance while excavating. Ants feed on everything from sugar, fruits, meats, seeds, vegetables, and fungi. Ferrets make very good house pets, especially due to their adorable playfulness. In their natural habitats, they prefer excavating multi-channelled burrows to rest and reproduce. Being carnivorous, ferrets feed on small mammals, which mostly include mice and rabbit. They can very efficiently chase these animals out of their burrows and hunt them. Although slow worms look like tiny snakes, they belong to the lizard family. As their name suggests, they are slow moving and are game to birds, badgers, foxes, and hedgehogs. Slow worms mostly burrow in warm areas like grasslands and woodlands. These worms feed on caterpillars, spiders, and earthworms. Being very common worms, earthworms dwell in loamy soil. They contract and expand their bodies for the purpose of locomotion, which also helps them burrow into the soil. They feed on living or dead organic matter, and are also responsible for soil fertility. Hamsters are cheeky little rodents which feed on seeds, fruit, vegetation, and burrowing insects. Their elongated cheek pouches help them to carry food to their burrows. Their burrows are smartly constructed with separate chambers for nesting, food storage, and defecation; burrows will typically have several entrances. Hamsters are very popular as pets, especially Syrian hamsters. Meerkats belong to the mongoose family, and possess the unique ability to stand upright. They are native to southwestern Africa and exist in clans. All clans have interconnected dens, which they vacate during daytime and scavenge for food. The dens have several entrances, which are easily accessible in case of oncoming danger.
