Cats instinctively hide illness and pain. This guide covers the subtle signs Macau apartment owners should watch for, the conditions that most often get missed, and when to bring your cat in.
Cats are evolutionarily wired to hide pain. In the wild, showing weakness invites predation, and the instinct persists strongly even in well-fed house cats. In Macau's indoor-only apartment population, this creates a real problem: by the time a cat visibly limps or stops eating, the underlying condition is often advanced. This guide from Royal Veterinary Center explains the subtle behavioural changes to watch for, the conditions that most often get missed, and the practical observation you can do at home to catch problems early.
Why cats hide pain so well
The feline survival strategy is to appear normal until they cannot, and even then to withdraw rather than vocalise. Many painful conditions in cats progress slowly — osteoarthritis, dental disease, urinary tract inflammation, chronic kidney disease — and the cat simply adapts, moves less, jumps lower, and sleeps in easier-to-reach spots. Owners often describe the eventual diagnosis as 'he just seemed off recently', not realising the changes have been building for months or years. This is why annual wellness bloodwork and a careful physical exam are so important for cats, especially from age 7 onwards.
The subtle signs worth watching for
Behavioural changes are the earliest indicator. Watch for: a cat that no longer jumps onto the kitchen counter or favourite shelf, hesitates before jumping, or lands awkwardly; reduced grooming, especially along the back and hindquarters, leading to a matted or scruffy coat; increased hiding or sleeping in unusual places; irritability when touched in specific areas (the back, the hips, the mouth); changes in litter box habits — going more often, straining, vocalising while urinating, or eliminating outside the box; and a quiet overall 'slowing down' that owners often attribute to age. Any of these, especially in combination, warrants a check-up. Cats are not 'just getting old' when they slow down — there is almost always a treatable cause.
The conditions we most often catch late
Three problems show up repeatedly in older apartment cats where the owner only noticed something was wrong a few weeks before diagnosis. The first is chronic kidney disease: increased thirst, more urine in the litter box, weight loss and a dull coat. The second is dental disease: bad breath, dropping food, chewing on one side, pawing at the mouth, drooling. The third is osteoarthritis, especially in the hips, elbows and lower spine: reluctance to jump, stiffness after rest, reduced grooming because twisting hurts. All three are manageable when caught early, and all three become much harder to treat when caught late. Routine bloodwork, dental exams and a hands-on orthopaedic check are how we find these early.
A simple at-home observation routine
Twice a month, spend 2-3 minutes watching your cat move and behave. From the side and from above, look at body condition — ribs easily felt, waist visible, no saggy belly. Watch a jump onto a low surface and back down — smooth and four-paw landing, or hesitation and a half-jump? Run your hands along the back, hips and legs; flinch response or muscle tensing suggests pain. Lift the lip briefly and look at the teeth — heavy tartar, red gums, or a broken tooth warrants a closer look. Check the litter box for changes in clump size, frequency or colour. None of this is diagnostic, but changes between observations are a clear signal that a vet visit would be valuable. Bring your observations with you — they often tell us as much as the exam itself.
When to come in right away
Bring your cat to Royal Veterinary Center without delay if you observe any of the following: straining to urinate with little or no output (this is a true emergency in male cats), sudden collapse, persistent vomiting, refusal to eat for more than 24 hours, sudden lameness or inability to use a limb, visible bleeding, or any acute breathing difficulty. Our 24-hour emergency line (+853 6677 6611) is always available. For non-urgent changes — slower jumping, new irritability, litter box changes, weight loss, dull coat — book a wellness consultation and bring your home observations. The earlier we see a problem, the more options we have and the better the long-term outcome.
