The American Shorthairs were originally mice hunters who killed mice in ships but eventually protected crops from small rodents. Nowadays, these cats use their hunting instincts for play and entertainment.

American Shorthair cats are loving and affectionate towards their owners, although they do not demand constant affection. They enjoy and are often content with hanging around with their family. They also do not mind being carried and held, even by kids.

Despite their origins as working cats and their muscular stature, American Shorthair cats are friendly and playful creatures that get along well with people as well as other animals. They are easygoing cats that enjoy playing with their families.

VetStreet describes American Shorthair cats as social animals that enjoy company, but they are not very talkative. Instead, they tend to use their body language to convey their emotions and their needs.

Are American Shorthair Cats Low Maintenance?

American Shorthairs are relatively easy to maintain. The most important part of maintaining an American Shorthair is to brush them as necessary.

A weekly brushing for American Shorthairs is recommended, especially when your cat is shedding. Frequent brushing will remove all dead hair, dirt, and mats that accumulate on the cat’s fur and keep your cat from spreading its hair all over your home.

Regularly brushing your cat is also essential because it helps spread the natural oils on your cat’s skin, allowing it to grow a healthier coat or fur. If you want to know more about how often you should groom your pet cat, read through this post: How Often Should You Brush Cats?

Aside from regular brushing, you should also trim your cat’s nails when they get too long. You need to clean their ears once a week to prevent the buildup of dirt that could cause ear infections. The National Cat Groomers of America also recommends bathing and blow-drying your cat every 4 to 6 weeks.

Do American Shorthair Cats Have Health Problems?

American Shorthair is generally a healthy breed, but they are prone to certain diseases and ailments. These cats are very susceptible to some conditions such as periodontal disease, heart disease, and hip dysplasia.

Despite being a playful breed, American Shorthair cats are only moderately active felines. Due to their inactivity, these fur friends are at a high risk of weight gain and obesity.

Potential excess fat in these cats has a huge effect on their health and lifespan. Obesity increases the risks of developing heart disease and hypertension, osteoarthritis, diabetes, cancer, and urinary bladder stones.

Because of their risks of obesity, American Shorthair cats should be kept on a diet and should not be overfed. It would be best to measure out their meals instead of free-feeding them.

If your American Shorthair is overweight, you can try using slow feeder bowls to prevent them from eating their meals all at once. It will also help if you use a toy your cat likes the most to get them running and jumping around as much as they can.

You can take advantage of their hunting instincts to increase their activity. Being natural predators, American Shorthairs enjoy “hunting,” even if it only means prey-shaped lures or laser pointers. You can engage your ASH in these kinds of interactive play to make them burn extra calories.

Aside from keeping watch over their weight, your American Shorthair can live a long, happy life. Full and updated vaccinations, regular exercise, neutering or spaying, nail and dental care, and a balanced diet will help keep your cat healthy and allow you to spend nearly two decades with them.
