Senior cat care: subtle signs owners should track

Quick answer: Track water consumption, monthly weight, litter box habits, jumping or climbing ability, grooming, and behavior changes. Senior cats need vet visits every 6 months. Bring written notes — even rough ones — because catching kidney disease, hyperthyroidism, or diabetes early changes the trajectory.

Cats evolved as small predators who also got hunted; showing weakness invited attack. That instinct means by the time a cat looks obviously sick, the condition is usually advanced. The owner’s leverage is paying attention to the boring, subtle drift — the half-bowl-more of water, the slower jump to the couch, the missed grooming on the back. None of this is dramatic. All of it matters.

Water intake

Increased thirst is one of the earliest signs of chronic kidney disease, diabetes, and hyperthyroidism — all common senior cat conditions. If you notice your cat drinking more, refilling the water bowl more, or seeking the bathroom faucet more often, write it down with a rough estimate and bring it to your vet.

Weight

Weigh your cat monthly. A kitchen scale or a baby scale works for most cats. Senior weight changes:

• Weight loss with normal or increased appetite — classic for hyperthyroidism, also seen in diabetes.
• Weight loss with decreased appetite — many possible causes; needs a vet visit promptly.
• Weight gain — often from changes in activity level; can also signal certain conditions.

For the broader weight context, see pet weight tracking: why your vet asks about weight changes.

Mobility

• Hesitating before jumping up to a favorite spot.
• Choosing lower perches than before.
• Taking the steps slowly when previously running them.
• Avoiding stairs entirely.
• Stiffness after sleeping.

Cats hide pain. Behavioral changes in mobility often precede limping. Arthritis is increasingly recognized as common and undertreated in senior cats — ask your vet about it specifically.

Grooming

Decreased grooming — especially on the back half — can signal pain, dental issues, or systemic illness. A previously fastidious cat with matting on the rear is sending you information. Increased over-grooming in spots can also signal a problem.

Litter box habits

Senior cats often signal illness through the litter box:

• Larger or more frequent urine clumps — possible kidney disease or diabetes.
• Smaller or less frequent urination — possible obstruction (especially in male cats; an emergency).
• Urinating outside the box — behavioral or medical; vet should rule out medical first.
• Diarrhea or constipation.
• Blood in stool or urine.

For more, see litterbox changes as a vet-visit signal.

Behavior

• Vocalizing more, especially at night.
• Hiding more than before.
• Becoming clingy when previously independent (or vice versa).
• Confusion in familiar spaces — can signal feline cognitive dysfunction in very old cats.
• Decreased interest in play or food puzzles.

The 6-month wellness visit

Senior cats benefit from twice-yearly wellness visits. Typical workup includes physical exam, weight, blood pressure, bloodwork (especially kidney values, thyroid, glucose), and urinalysis. Bring your tracking notes — even sticky-note level. “She started drinking more water around mid-March” is more useful than “she’s drinking more” in the exam room.

Where Driyu fits, honestly

A Driyu profile gives you a single place to keep monthly weight notes, medication reminders, and vet contact info for your senior cat. Bring it up on your phone at the wellness visit instead of digging through your camera roll for that one weight number from October.
