Small mammals are among the most common animals hunted by domestic and feral cats. From tiny field mice hiding in long grass to voles living beneath hedgerows, these creatures provide natural hunting opportunities for cats in many environments. Although pet cats may receive regular meals at home, their instincts to stalk, chase and catch small animals remain strong. Understanding which mammal’s cats hunt helps explain feline behaviour and the relationship between domestic cats and local wildlife.
Mice: A Favourite Target for Cats
Mice are among the most frequently hunted mammals because of their small size, quick movements and widespread distribution. House mice often live near buildings, farms and gardens, while field mice and wood mice occupy grasslands, hedgerows and woodland edges.
Cats use their excellent hearing to detect the faint sounds of movement. They may crouch low to the ground, watch carefully and slowly approach before making a sudden leap. Their sharp claws and teeth help them catch and kill their prey.
For some cats, hunting mice provides an opportunity to practise natural predatory behaviour, even when they are not hungry.
Rats: Larger and More Challenging Prey
Rats can also become prey for cats, although they present greater challenges than mice. Adult rats can be large, strong and capable of defending themselves with powerful teeth. An encounter may result in injuries to the cat, particularly if the rat is cornered.
Some cats will avoid large rats and concentrate on smaller animals instead. Others may attempt to catch young rats or smaller individuals.
Rats are commonly found around farms, rubbish storage areas, drains and buildings where food is available. Owners should avoid encouraging cats to hunt rats, especially where rodents may have been exposed to poison. Eating a poisoned rodent can potentially expose a cat to rodenticides, so suspected exposure requires urgent veterinary advice.
Shrews: Tiny Mammals With Big Appetites
Shrews are small mammals that resemble mice but belong to a different animal group. They have pointed snouts, tiny eyes and very high energy requirements.
Shrews eat a variety of small invertebrates, including insects and worms. Their constant movement can attract a cat’s attention, making them vulnerable to hunting.
However, cats do not always eat shrews after catching them. Some shrews produce strong-smelling secretions that may make them less appealing as food. Their ecological importance also means that protecting their habitats can benefit gardens and wider wildlife.
Voles and Other Small Mammals
Voles are another common type of cat prey. These small rodents often live in grasslands, meadows and field margins, where they feed on vegetation and seeds. Their tunnels and runs provide shelter, but cats can detect their movements and wait near entrances.
Depending on the region, cats may also catch young rabbits, juvenile squirrels and other small mammals. The species encountered will vary according to local habitats, seasons and prey availability.
The Impact on Wildlife
Cats are skilled predators, but hunting can affect local wildlife populations, particularly where vulnerable species are already under pressure. The impact varies between environments and depends on the number of cats and the abundance of prey.
Owners can help reduce unnecessary wildlife deaths by keeping cats indoors during vulnerable periods, supervising outdoor access and providing secure enclosures. Play sessions with fishing-rod toys and other suitable activities can also provide valuable stimulation.
Understanding Cats’ Hunting Instincts
Mice, rats, shrews, voles and other small mammals demonstrate the diversity of animal’s cats may hunt. These behaviours are deeply rooted in feline biology and can occur even when a cat is well fed.
By understanding these instincts, cat owners can provide enriching activities that support their pets’ natural behaviour while taking practical steps to protect wildlife.
