Common Health Issues in Cats Australia — What to Watch For

Whether your feline friend is a sun-basking indoor tabby or an adventurous outdoor cat, knowing the health risks they might face is key to giving them a long, purring life. Australia presents some unique challenges — from parasites and environmental risks to diseases that often go unnoticed. In this post, we take a look at the most common health issues affecting cats across the country, how to spot them, and when it’s time to call the vet.

Most Common Health Issues for Australian Cats

Kidney problems & urinary-tract issues

Kidney disease is a serious concern for many cats, especially as they age. According to pet care sources, chronic kidney disease and urinary-tract problems (such as Feline Lower Urinary Tract Disease, or FLUTD) are among the common ailments vets treat.

Watch for signs such as increased thirst and urination, weight loss, reduced appetite, vomiting or lethargy. Early detection — including regular vet check-ups — can help manage the condition.

Digestive issues, vomiting & diarrhoea

Digestive upsets — including vomiting, diarrhoea and gastrointestinal infections — are common in cats.

These can be triggered by abrupt diet changes, food intolerances or infections. Persistent or severe symptoms warrant a vet visit, because they can indicate deeper problems.

Dental disease

Dental problems (gum disease, tartar build-up, tooth decay or resorption) are frequently under-diagnosed in cats but can affect quality of life severely.

Look out for bad breath, drooling, pawing at the mouth or difficulty eating. Regular dental checks during vet visits can catch early warning signs.

Skin, parasites — fleas, ticks, mites, ringworm & allergies

Australia’s climate and fauna mean cats can be at risk from parasites and skin conditions, including flea infestations, ticks (including the paralysis-tick species Ixodes holocyclus), mites, fungal infections like ringworm, or allergic dermatitis.

Regular flea/tick prevention, grooming, and checking coat and skin regularly can help. If you notice excessive scratching, skin irritation, hair loss or lethargy — get your cat to the vet.

Obesity and associated risks (diabetes, arthritis, heart issues)

Overweight cats are more vulnerable to a host of health problems such as diabetes (a possibility in cats), arthritis, heart or kidney disease.

Maintaining a healthy weight via balanced diet and regular play or exercise helps — particularly for indoor cats.

Chronic or serious diseases — cancers, immune-related diseases, FIV/FeLV etc.

Sadly, as cats get older they may be vulnerable to serious conditions such as cancers, immune-system diseases (like Feline Immunodeficiency Virus (FIV) or Feline Leukaemia Virus (FeLV)), or other chronic illnesses.

These diseases may develop gradually — so regular vet check-ups, good preventive care, and monitoring for subtle changes in behaviour, appetite or weight are vital.

Prevention & What You Can Do as a Cat Parent

• Regular vet check-ups: Early detection is a top defence. Schedule annual or bi-annual check-ups depending on your cat’s age and health history.
• Good diet + proper portion control: Keep your cat at a healthy weight to avoid obesity-related illnesses.
• Parasite prevention: Use flea, tick and worm preventatives — especially if your cat spends time outdoors.
• Dental care: Consider regular dental checks and home-care (brushing, dental diets or treats).
• Safe home environment: Keep toxic plants, dangerous household items or chemicals out of reach; provide clean water, safe litter trays, and mental stimulation.
• Watch for warning signs: Unusual drinking/urination, weight loss, changes in appetite or behaviour, vomiting, lethargy, skin issues — when in doubt, consult a vet.

Keeping on top of your cat’s health — with good care, prevention and regular vet visits — goes a long way toward a happy, healthy life together. And if you want peace of mind and help paying for unexpected vet bills, it’s worth exploring pet insurance early.
