The Truth Behind Common Cat Health Myths

Purring is often a sign of contentment, but it is also a self-soothing behavior. Veterinarians routinely observe cats purring during painful procedures or when experiencing significant distress. Some research suggests the vibration frequency of purring (roughly 25–150 Hz) may have physiological benefits — including promoting bone density — which could explain why cats purr when they need internal calming as much as when they are comfortable.

If your cat is purring while also hiding, refusing food, or showing other behavioral changes, those accompanying signs matter more than the purr itself. See our article on recognizing stress in cats for a fuller picture.

Cats possess a vestibular-driven righting reflex that allows them to rotate their body mid-fall and orient their feet downward. This is a genuine, well-documented physiological ability. However, it requires enough air time to activate fully, and it does not absorb the impact of landing. Falls from low heights (one to two stories) can paradoxically cause more injury than very high falls because the cat doesn't have time to fully orient and relax its muscles.

High-rise syndrome — a recognized veterinary presentation — includes injuries such as fractured limbs, jaw fractures, and internal trauma. Window screens and balcony barriers are important safeguards, not optional accessories.

Kittens produce lactase, the enzyme needed to digest lactose in their mother's milk. Most cats lose significant lactase activity after weaning. Offering cow's milk — which contains far more lactose than queen's milk — frequently leads to diarrhea, gas, and abdominal discomfort. The image of a cat happily lapping milk is cultural shorthand, not nutritional guidance.

Cats that do tolerate small amounts of dairy without visible symptoms may still experience low-grade gastrointestinal irritation. Fresh water remains the safest and most appropriate liquid for adult cats.

Pathogens can enter a home on clothing, shoes, or through brief contact with other animals — for example, if a cat escapes outside momentarily or a second pet is brought in. Feline panleukopenia, calicivirus, and herpesvirus are all highly stable in the environment and can survive on surfaces. Core vaccines protect against diseases where exposure risk, while reduced indoors, is not zero.

Vaccine schedules for adult cats also vary based on individual risk factors, and many municipalities have legal requirements for rabies vaccination regardless of lifestyle. A veterinarian can help determine the appropriate protocol for your specific cat.

Hyperthyroidism, one of the most common endocrine diseases in older cats, frequently causes increased hunger alongside weight loss. Early chronic kidney disease may show minimal appetite changes until the condition has progressed considerably. Diabetes can also present with increased eating before more obvious symptoms appear.

Good appetite is reassuring but not a reliable health proxy on its own. Regular veterinary checkups with bloodwork provide far more diagnostic information than appetite observation alone — particularly for cats over seven years of age.

While cats are more independent than dogs in many respects, they are not asocial by nature. Feral cat colonies demonstrate complex social structures, and domestic cats form meaningful bonds with human caregivers. Under-stimulation in indoor environments is a recognized contributor to feline stress, boredom-related behaviors such as over-grooming, and obesity.

Environmental enrichment — including climbing structures, puzzle feeders, and scheduled interactive play — addresses these needs practically. Our guide to indoor cat enrichment outlines strategies grounded in current animal behavior research.
