Domestic Shorthair cat care guide (Australia)
The Domestic Shorthair is PetGuides.au's easiest-keeping cat for most Australian homes: a mixed-background moggy, not a fixed breed, so temperament varies cat to cat. Expect a 12–18 year companion that thrives indoors or in a cat run, needs only weekly brushing, and whose real care is dental checks and a steady weight.

Is a Domestic Shorthair right for your home?
"Domestic Shorthair" is not a pedigree breed — it is the catch-all for Australia's everyday moggy, a mixed-ancestry shorthaired cat with no breed standard behind it. That matters when you choose one: you are picking an individual, not a predictable type. The bold tabby at the shelter and the shy black-and-white in the next pen may share the label and share almost nothing else in personality.
This works in your favour. Because the gene pool is so broad, Domestic Shorthairs are generally hardy and adaptable, and most settle into indoor Australian life — apartments, townhouses, family homes — without the high-maintenance grooming or fixed-breed quirks of a pedigree. They suit first-time cat owners, renters who can keep a cat contained, and households that want a low-fuss companion.
They suit you poorly if you want a guaranteed personality off a breed page — a moggy can't promise the lap-cat calm of a Ragdoll or the talkative clinginess of a Siamese. Meet the actual cat, ask the shelter or foster carer how it behaves, and choose on the animal in front of you rather than the two-word label.
Living with a Domestic Shorthair in Australia
The single biggest decision is containment. Across much of Australia, councils encourage or require cats to be kept on the owner's property, and a growing number have cat curfews or full containment rules — partly for native wildlife, partly because a contained cat lives longer and avoids cars, fights, snakes and ticks. A Domestic Shorthair adapts to indoor or cat-run life readily; check your own council's cat rules before you assume free roaming is allowed.
A contained cat needs you to bring the outdoors in. Give it vertical space (a tall scratching post or shelf by a window), daily play that lets it chase and pounce, and enough litter trays — the usual guide is one per cat plus a spare. A bored, under-exercised indoor cat is the one that overeats and gains weight, which feeds straight into the health risks below.
In an Australian summer, even an indoor cat feels December–February heat: leave fresh water in several spots, provide a cool tiled or shaded place to lie, and never shut a cat in a sunroom or car. If yours has any outdoor access in tick country on the east coast, the paralysis tick (Ixodes holocyclus) is a genuine danger — talk to your vet about prevention and learn to check the coat.
Grooming a Domestic Shorthair: what it really takes
The short coat is the easy part. A weekly brush with a soft slicker or grooming glove lifts loose hair and dander, and that is genuinely most of what a Domestic Shorthair needs — they are self-cleaning cats and rarely need bathing. Step up to a few times a week during the seasonal moult, which in Australian homes tends to ramp up as the weather warms, when these cats shed noticeably more.
What owners underestimate is that brushing is less about the coat looking tidy and more about what goes into the cat's stomach. A cat that swallows a season's worth of loose hair while self-grooming brings up hairballs; regular brushing removes that hair before the cat does. It is also your weekly minute to feel for lumps, fleas, ticks (in tick areas) and matting around the back end on an older or overweight cat that can no longer twist to clean itself.
Use the same routine to glance at the teeth and gums and to check the claws — indoor cats don't wear claws down on pavement, so keep a scratching post available and trim tips if they catch on carpet.
Domestic Shorthair health: what to watch for
A Domestic Shorthair can share a home with you for 12–18 years, and most of that span is healthy if you stay ahead of a handful of common cat problems. None of the below is a diagnosis — it is what to watch for and what to raise with your vet at a check-up.
- Dental disease: tartar, red gums and painful tooth resorption are among the most common problems in cats and easy to miss because cats hide pain. Early signs an owner notices: bad breath, dropping food or chewing on one side, drooling, or pawing at the mouth. Ask your vet to check the teeth at every visit and whether a dental clean or home dental care is due.
- Obesity: a contained, well-fed moggy gains weight quietly, and extra kilos drive arthritis, diabetes and urinary trouble. Early signs: you can no longer easily feel the ribs, a sagging belly, less jumping, or struggling to groom the back half. Ask your vet to body-condition score your cat and to set a feeding amount — free-feeding a bowl all day is the usual culprit.
- Chronic kidney disease: very common in older cats, where the kidneys slowly lose function over months to years. Early signs: drinking much more, weeing more, weight loss and a duller coat in a senior cat. Ask your vet about senior blood and urine checks from middle age, since catching it early changes how well it's managed.
- Lower urinary tract disease: irritation or blockage of the bladder and urethra, which can become a genuine emergency — a male cat straining and unable to pass urine needs a vet immediately. Early signs: frequent trips to the litter tray, straining, crying, blood in the urine, or weeing outside the tray. Ask your vet about water intake, stress and diet, and never wait it out if your cat can't urinate.
Keeping the cat lean, the water flowing and the teeth checked covers most of what threatens these years.
The real cost, and your first 90 days
A Domestic Shorthair is one of the cheapest cats to acquire — they fill Australia's shelters and rescues, so adoption fees are modest and usually bundle desexing, microchipping and a first vaccination. The ongoing costs are where the money sits, and they are the same drivers as any cat: quality food, annual vaccination and health checks, year-round parasite prevention (and tick prevention if you're on the east coast), litter, and ideally pet insurance taken out while the cat is young and healthy. The two avoidable big-ticket costs both appear above — a dental procedure and an emergency urinary blockage — which is exactly why the weight, water and dental basics pay off. For current local figures, use the tools below rather than guessing.
First 90 days checklist: - Book a vet health check and confirm desexing, vaccination and parasite-prevention are up to date. - Confirm the microchip is registered to you and update your details. - Check your council's cat containment and registration rules and comply. - Set up litter trays (one per cat plus one), scratching posts and vertical space indoors. - Settle on a measured feeding amount with your vet instead of leaving food out all day. - Start a weekly brush-and-check habit so you notice changes early.
Common questions about Domestic Shorthairs in Australia
Is a Domestic Shorthair the same as a moggy?
Yes. "Domestic Shorthair" is the formal label for Australia's everyday shorthaired moggy — a mixed-ancestry cat with no pedigree or breed standard. It tells you the coat is short and the background is unknown, not the personality. Because of that broad gene pool they're generally hardy and adaptable, but you should always choose based on the individual cat's temperament, not the label.
Can I keep a Domestic Shorthair as an indoor cat in Australia?
Absolutely, and many Australian councils now encourage or require it through cat containment rules and curfews. Domestic Shorthairs adapt well to indoor or cat-run living. Give them vertical space, daily play, scratching posts and enough litter trays, and watch their weight — a contained, under-exercised cat is the one most likely to overeat. Check your own council's cat rules before deciding.
How often should I brush a Domestic Shorthair?
A weekly brush is enough for most of the year, stepping up to a few times a week during the seasonal moult when shedding increases. The short coat is low-maintenance, but regular brushing matters less for looks and more for removing the loose hair your cat would otherwise swallow into hairballs — and it's your chance to check for fleas, ticks, lumps and matting on older cats.
What health problems should I watch for in a Domestic Shorthair?
The common ones are dental disease, obesity, chronic kidney disease and lower urinary tract disease. Watch for bad breath or trouble eating, creeping weight gain, a senior cat drinking and weeing more, or any straining in the litter tray. A male cat straining and unable to pass urine is an emergency — see a vet immediately. Regular check-ups and a lean weight prevent most trouble.
How long do Domestic Shorthair cats live?
Typically 12–18 years, and often the upper end of that with good care. Their mixed background tends to make them hardy, and a contained indoor or cat-run life avoids many early deaths from cars, fights and disease. The biggest levers on a long life are keeping the cat at a healthy weight, staying on top of dental health, and routine vet checks — especially senior blood and urine screening as they age.
