Can Cats Kill Weasels? Dangers, Facts & FAQ

The debate over whether a cat or a Weasel would win in a fight has been around for years, and it’s a valid question if you have a pet Weasel in your home with a cat or other small animals. Whether a cat can kill a Weasel depends on the cat’s weight and size and whether they are fighting to the death. Although the odds favor the cat, Weasels are known for being aggressive animals that hunt and eat smaller animals constantly, including small cats.

So, there’s no clear answer as to who would win. Can a cat and a Weasel live in the same house? There’s no clear-cut answer, either. However, we’ll answer your questions the best we can below.

What Does a Weasel Look Like?

Weasels and Ferrets are cousins and look a bit alike. The Weasel and Ferret are part of the Mustela family. They usually range from 4 to 12 inches long and have colors such as brown, gray, or black and white with tan markings that turn all white during winter.

Weasels Are a Danger to Small Pets

Weasels hunt smaller animals for food, so they are a danger to small pets, including cats in your household. Pets that your Weasel may go after to kill and eat are cats, gerbils, rabbits, and small dogs. It’s not a good idea to have a Weasel living in the same house with other small pets, so if you give a Weasel a forever home, you might need to choose between the two.

Another animal related to the Weasel, the Pacific Fisher, is not suitable to keep as a pet, and in the United States, they’re illegal to own. The fur trade nearly decimated them in the 19th century, but the population has rebounded, and they have been spotted in Massachusetts, New York, and New Jersey. If you live in one of those states and own a cat, keep them indoors. Fishers are skilled hunters who kill chickens, rodents, and small cats.

Pet Weasels Could be Illegal Where You Live

Some Weasel species are on the list of endangered, threatened, or species of concern. They were placed there by the United States Fish and Wildlife Service, and it could be illegal for you to own a Weasel in your area.

In fact, Weasels and ferrets are illegal to own as pets in California and Hawaii. Some counties and cities in other states have various rules about keeping Weasels, and many have banned them. You’ll need to check with your local animal enforcement agencies in your state and county to ensure owning a Weasel isn’t illegal in your area before you decide to get one as a pet.

Weasels as Pets May Not be the Best Idea

Keeping a Weasel as a pet isn’t the best idea. Pet parents with other small pets shouldn’t own a Weasel because they attack and kill them. If you want a pet in the Mustela family, you might want to adopt a ferret instead. We’ll discuss the differences between a Ferret and a Weasel in the section below.

What Are the Differences Between a Ferret and Weasel?

There are a few fundamental differences between a Ferret and a Weasel. It’s easy to find a ferret breeder, and they may be a better choice for you and your family, especially if you have other small pets such as cats, rabbits, or small dogs.

Here are the differences of note between the two.
  • Ferrets have longer tails and shorter bodies than Weasels
  • Weasels are wild, while Ferrets are more domesticated
  • Ferrets have black and brown coats that are mixed with white
  • Weasels are awake and play during the day, while Ferrets are nocturnal creatures

Having a pet Weasel isn’t a good idea for many reasons, and if you have a cat, they may not win a fit with one, depending on their size and defensive skills. Weasels are wild and are not fond of living in captivity. They also hunt smaller animals, which includes domestic cats. While a cat might be able to kill a Weasel, a Weasel has sharper claws that can cause serious harm to felines. The last thing you want is to bring an animal into your home that might kill your pets or be killed by them.

A Ferret is a much better option for keeping as a pet since they’re tamer, and it is illegal to own a Weasel as a pet in many areas. Before adopting an exotic pet like a Weasal, check your local and state laws to ensure they’re not illegal.
