About American Shorthairs
The American Shorthair (often called "Ame-Sho") is a medium-sized cat breed native to America, descended from working cats that migrated from Europe to the Americas in the 17th century. While the beautiful marble pattern of silver tabby is the most famous, in reality over 80 color variations are recognized.

The American Shorthair is known as a representative example of an "easy-to-keep cat breed."
Gentle and calm: They rarely vocalize loudly, making them well-suited to apartment living
Affectionate yet independent: They don't particularly like sitting on laps; they prefer a "nearby" style
Good compatibility with children and other animals: High social nature makes multi-cat households and living with dogs smooth
Moderate hunting instinct: They enjoy toy play, which is effective for preventing indoor boredom
Required Living Environment
Living Space
American Shorthairs are active cats, but they prefer frequent short play sessions over strenuous exercise.
Cat tower: Install to satisfy their natural desire for high places
Scratching posts: Scratching habits are important for furniture protection. Place in multiple locations
Hiding spots: Secure resting spaces such as cardboard boxes and cat tunnels
Temperature and Seasonal Management
Ideal temperature: 18-26°C
Winter: Install heaters and address humidity control
Summer: Air conditioning is essential to prevent heat stroke (risky even indoors)
Their dense coat provides some insulation, but they are vulnerable to excessive heat.
Diet Management
American Shorthairs tend to have robust appetites and are prone to obesity. Maintaining appropriate weight is the secret to longevity.
Recommended Diet
Diet Type
Benefits
Notes
High-protein, low-carb dry food
Prevents tartar buildup, long shelf life
Need to increase water intake
Wet food (canned/pouch)
Hydration, high palatability
Watch for excessive calories
Homemade food
Fresh ingredients
Nutritional balance is difficult (vet consultation recommended)
Ideal combination: Use dry food as the main diet and wet food as occasional topping to encourage water intake.
Daily Feeding Amount Guide (Dry Food)
Weight
Daily Amount
3 kg
50-65g
4 kg
65-80g
5 kg
80-95g
6 kg
95-110g
Note: Varies by food type and calorie density. Follow package instructions and check weight changes monthly to adjust.
Key Points for Obesity Prevention
"Free feeding (leaving food out constantly)" carries high obesity risk
We recommend time-restricted feeding, offering meals 2-3 times daily at set times
Keep treats to 10% or less of main meal calories
Coat Care and Daily Grooming
Brushing
Their short, dense coat sheds heavily during shedding seasons (spring and fall).
Shedding season (March-May, September-November): Ideal to brush 3-5 times weekly
Normal season: 1-2 times weekly is sufficient
Since they have a thick undercoat, a combination of a comb and slicker brush is effective.
Other Grooming
Care
Frequency
Tips
Nail trimming
Monthly to bi-monthly
Acclimate from kittenhood
Teeth brushing
Ideally daily, minimum 3 times weekly
Use dedicated toothbrush and paste
Ear cleaning
Approximately monthly
Wipe with cotton, not cotton swabs
Eye care
As needed
Wipe discharge with warm cotton
Health Management and Breed-Specific Risks
Hypertrophic Cardiomyopathy (HCM)
American Shorthairs are known as one of the breeds with high risk for hypertrophic cardiomyopathy (HCM).
Symptoms: Initially asymptomatic; as it progresses causes difficulty breathing, loss of appetite, and lethargy
Age of onset: Typically develops around 4-8 years old
Management: Regular echocardiograms (recommended every 1-2 years)
To reduce HCM risk, the most effective measure is to purchase from breeders who perform HCM testing on parent cats (including ultrasound and genetic testing).
Other Conditions to Watch
Condition
Description
Obesity-related diseases
Diabetes, arthritis, hepatic lipidosis
Feline lower urinary tract disease (FLUTD)
Triggered by stress and insufficient water
Skin conditions
Atopy, mite infestation
Vaccinations and Prevention
3 or 5-in-1 combination vaccine: Annually or every 3 years (consult with veterinarian)
Rabies vaccine: Some veterinarians recommend even for completely indoor cats
Heartworm, flea, and tick prevention: Recommended even for indoor cats
Points When Purchasing from Breeders
Because American Shorthairs are popular, disreputable mass breeding operations (puppy mills, cat mills) exist. When using breeder direct sales services such as Br-Choku, confirm the following:
HCM testing: Presence of echocardiogram and genetic testing (MyBPC3) certificates for parent cats
Pedigree registration (CFA, TICA, etc.): Issuance of official pedigree certificates
Disclosure of breeding environment: Hygiene conditions and number of cats in the cattery
Age at handover: 12 weeks or older indicates completion of socialization
Summary
American Shorthairs are considered an "ideal easy-to-keep cat breed" in many respects: hardy, long-lived, gentle temperament, and beautiful color variations. However, attention must be paid to their obesity tendency and cardiomyopathy risk. By following three key points—proper weight management, regular health check-ups, and purchasing from breeders with verified HCM testing—you can enjoy nearly 20 years together.
