What You'll Learn
Fisher cats' predatory nature
Fishers, sometimes called "fisher cats", are shy and solitary predators that prefer to avoid humans. They are native to North America and are members of the weasel family. While they are known to prey on small animals, their reputation as vicious predators is largely unfounded.
Fishers are opportunistic and generalist predators, feeding on whatever is readily available. Their diet includes small to medium-sized mammals, such as mice, squirrels, birds, reptiles, amphibians, and insects. They are also known to consume fruits and mushrooms. Despite their name, fish are not a regular part of their diet.
While fishers are capable of preying on cats and small dogs, they usually prefer smaller prey. Studies examining the stomach contents of fishers have found cat remains in a very low percentage of samples. In one study in Massachusetts, out of over 1,000 fisher stomachs examined, only one contained cat hairs. This suggests that cats are eaten by fishers much less frequently than commonly believed.
Fishers are crepuscular, with heightened activity during dawn and dusk. They are agile climbers but spend most of their time on the forest floor, foraging around fallen trees. They reside in coniferous or mixed hardwood forests, particularly those with higher concentrations and varieties of prey.
Although unprovoked attacks on humans are extremely rare, fishers will defend themselves if they feel threatened or cornered. They are strong and fierce animals, with powerful jaws and sharp claws, making them capable predators.
In summary, while fishers do possess predatory traits and behaviours, they are generally misunderstood and pose little threat to humans or pets. Their predatory nature is an integral part of maintaining healthy ecosystems, especially in controlling the population of certain prey species such as porcupines.

Dogs as guard animals
Dogs have been used as guard animals since ancient times. The Romans used mosaics at the entrance of houses to warn visitors and intruders of the presence of dangerous dogs. Livestock guardian dogs, such as the Kangal, are large enough to attack and drive away predators. They use loud alarm barks as a first line of defence, followed by displays such as bluffing and charging if the intruder does not retreat.
Some smaller dog breeds, such as the Keeshonden and Tibetan Terriers, are excellent watchdogs but not guard dogs due to their small size and lack of assertive behaviour. Watchdogs bark to alert their owners of an intruder's presence and to scare them away. Guard dogs, on the other hand, are capable of attacking and restraining intruders.
Guard dogs tend to be territorial, averse to strangers, dominant, and protective and loyal to their family. Some dog breeds commonly used as guard dogs include the Dobermann, Dogue Brasileiro, Fila Brasileiro, and Ovtcharka.
While dogs are the most common choice for guard animals, other animals can also be used for this purpose. For example, donkeys can be stationed with sheep to protect them from harm. They are appealing to ranchers because they do not require special feeding or care and can graze with the sheep. Donkeys can deliver crushing blows with their legs and large teeth to deter intruders.
In addition, geese have been used throughout history to guard properties, including a whisky distillery in Scotland and police stations in rural China. Their loud vocalizations can effectively scare off intruders.

Fisher cats' physical attributes
Fisher cats, also known as fishers, are native to the forests of North America. They are members of the weasel family and are characterised by their agile, carnivorous nature. While they do not typically pose a significant threat to humans, there have been rare instances of aggressive behaviour when they feel threatened or cornered.
In terms of physical attributes, fishers have long, thin, low-slung bodies, with males being significantly larger than females. Males can measure up to 120 cm in length and weigh up to 6 kg, while females typically reach 95 cm in length and weigh around 2.5 kg. Their fur changes with the seasons, becoming denser and glossier during winter, and they have retractable claws. Fisher cats are skilled climbers and swimmers, making them adept predators of small mammals, birds, and even porcupines.
The fisher's head and body length ranges from 47-75 cm, with a tail that adds an additional 30-42 cm. The colour of their fur ranges from deep brown to black, and it can appear even blacker during the winter months when contrasted with white snow. The underside of a fisher is mostly brown, with patches of white or cream-coloured fur. In the summer, their fur colour can lighten and become more variable.
Fishers have five toes on each foot, with large feet that aid in moving over snow. They possess highly mobile ankle joints, allowing them to rotate their hind paws almost 180 degrees, which is essential for their tree-climbing abilities. They also have retractable claws that do not hinder their movement when walking or running.
Overall, the physical attributes of fisher cats make them well-suited for their forest habitat and hunting lifestyle. Their size, agility, and sharp claws enable them to navigate their environment effectively and capture prey.

Attacks on humans
Fishers, sometimes called "fisher cats", are native to North America and are members of the weasel family. They are generally shy and solitary, preferring to avoid humans. They rarely attack people, and the few attacks that have occurred were likely defensive actions by cornered animals.
However, they are capable of preying on small pets like cats and dogs. There have been reports of fisher cats attacking dogs and cats, with some of these incidents resulting in severe injuries or even death. In one case, a fisher cat grabbed a puppy named Lucky by the neck and dragged him to a neighbour's yard before releasing him. Lucky required surgery to recover from his wounds.
To protect your pets from potential attacks, it is recommended to keep them on a leash when walking in wooded areas and never leave them alone outside. It is also important to remove bird feeders from your yard, as fisher cats are attracted to squirrels and other small animals that scavenge fallen bird seed.
If you encounter a fisher cat in your yard, you can scare it away using a water hose, loud noises, or bright lights. While they are not typically a threat to humans, it is still important to take precautions and avoid approaching or feeding them.
Overall, while fisher cats are generally not aggressive towards people, they can pose a danger to small pets, and it is important to take the necessary precautions to protect your animals.

Protecting pets from wildlife
Fishers, sometimes called "fisher cats", are often misunderstood creatures. Although they are typically shy and solitary, preferring to avoid humans, they have gained a reputation as vicious predators. This is largely due to their short muzzle, long whiskers, retractable claws, and bushy tails, which make them appear larger and more threatening than they actually are.
While they are capable of attacking and injuring pets such as dogs, these incidents are rare. In most cases, fishers will avoid confrontation and try to escape if they feel threatened. However, it is important to take steps to protect your pets from potential harm. Here are some ways to protect your pets from wildlife, especially fishers:
- Keep your pets indoors or supervise them when they are outdoors: This is the best way to ensure your pet's safety. If you cannot supervise your pet outdoors, consider installing a secure enclosure or run for them to play in.
- Secure food sources: Do not leave pet food outdoors, as this can attract fishers and other wild animals to your home. Similarly, keep garbage covered and bird seed off the ground.
- Be aware of your surroundings: If you live in an area with a known fisher population, be vigilant when walking your dog, especially at night or in wooded areas.
- Know the signs of a fisher: Familiarize yourself with the distinctive appearance and sounds of a fisher. Although they are typically quiet, they have been known to make screaming sounds when under extreme stress or in unusual circumstances.
- Protect your poultry: If you keep chickens or other poultry, take steps to secure their coops and prevent access to predators.
By following these precautions, you can help keep your pets safe from fishers and other wildlife. It is important to remember that while these animals are capable of causing harm, they are also an important part of the ecosystem and should be respected and protected.
