Common Cat Health Myths That Veterinarians Want You to Stop Believing

The feline righting reflex is real: cats can rotate their bodies mid-air to orient feet-downward. However, this reflex does not guarantee a safe landing. Veterinary emergency rooms regularly treat cats for fractures, jaw injuries, and pneumothorax (collapsed lung) following falls from windows or balconies — a syndrome sometimes called high-rise syndrome. Falls from intermediate heights (around two to six stories) can paradoxically be more dangerous than very high falls, because the cat may not have enough time to fully correct its position. Screens on windows and balcony barriers are important safety measures for cats in elevated living spaces.

Purring is widely misunderstood as a simple happiness signal. In reality, it is a self-soothing and communicative behavior that cats use across a wide range of emotional and physical states. Research suggests the frequency of a cat's purr (roughly 25–150 Hz) may even have mild self-healing properties for muscle and bone tissue — which could explain why cats purr when ill or in pain. Owners who assume a purring cat is fine may overlook signs of distress. If your cat is purring alongside unusual posture, hiding, or reduced appetite, those behaviors deserve closer attention. See our overview of feline stress signs for more context.

As solitary hunters by nature, cats instinctively mask signs of vulnerability — including illness or pain. By the time symptoms become obvious to an owner, a condition may already be well advanced. Annual wellness exams allow veterinarians to detect issues such as kidney disease, dental disease, hyperthyroidism, and diabetes at stages when intervention is far more effective. Our annual vet visit checklist outlines what to expect and what to ask at each appointment.

The image of a cat happily lapping up a saucer of milk is deeply embedded in popular culture — but it reflects a misunderstanding of feline digestion. After weaning, most cats produce significantly less lactase (the enzyme that breaks down lactose), making cow's milk difficult to digest. The result is often gastrointestinal discomfort, loose stools, or vomiting. Water is the appropriate primary beverage for cats. If you want to explore what your cat should actually be eating, our cat nutrition primer covers protein needs, wet versus dry food, and how to read ingredient labels.

It is easy to assume that a cat who never goes outside has no exposure to fleas, ticks, or viruses — but this is not accurate. Fleas can enter a home on clothing or other pets. Some infectious diseases, such as rabies, may be required by law to be vaccinated against regardless of lifestyle. Others, like feline herpesvirus, can be transmitted through indirect contact. Veterinarians tailor vaccine and parasite prevention protocols to an individual cat's risk profile, but indoor status alone does not eliminate the need for preventive care.

Cats have a reputation for being aloof, but behavioral research shows they form meaningful attachments to their owners and can experience boredom, loneliness, and stress when under-stimulated. Lack of enrichment is associated with behavioral problems such as excessive vocalization, destructive scratching, and overgrooming. Interactive play, puzzle feeders, vertical space, and consistent human interaction all support feline psychological wellbeing. If your cat is engaging in puzzling behaviors, our article on why cats knock things off tables offers a window into how feline instincts shape everyday behavior.
