Senior cat care: kidneys, thyroid and weight
Cats hide illness well, and they can lose weight so slowly that nobody notices. Bloodwork finds the common conditions long before they change your cat’s behavior.
Changes to watch for
Signs worth acting on
These are easy to blame on age, but several are signs of treatable conditions.
- Weight loss, even slow weight loss, in a cat still eating well
- Drinking more, or bigger clumps in the litter box
- Eating more but losing weight or muscle
- Sleeping more, jumping less, taking the stairs one step at a time
- A coat that looks unkempt, or grooming that has stopped
- Yowling at night, or restlessness
- Bad breath, or eating on one side
What we check
Kidney disease, thyroid disease and diabetes
Chronic kidney disease, hyperthyroidism and diabetes account for a large share of what we find in older cats, and all three are managed far better when they are caught early.
- Bloodwork and urine testing, done in-house during the visit
- Thyroid and kidney values
- Blood pressure, which matters alongside kidney disease
- Weight tracked against previous visits rather than judged by eye
- A full oral examination — dental pain is a common reason a cat eats less
- Ultrasound and digital X-ray on site when the exam suggests a problem
Why here
Low-stress handling at every visit
Senior cats come in more often, so gentle handling matters more. Animal Republic is a Gold-level Cat Friendly Practice®, certified by the American Association of Feline Practitioners (AAFP) and the International Society for Feline Medicine (ISFM) against standards for feline medicine, handling and hospital design.
Because our laboratory is on site, we discuss results at the visit, and you leave with a plan instead of waiting for a phone call. Senior cats are seen for a wellness examination and screening every six months, with more frequent rechecks when medically indicated.
Related problems
When an older cat stops eating, strains or has mouth pain
In older cats, a vague symptom is especially likely to have a specific cause.
A cat who has stopped eating needs to be seen sooner than a dog would: see not eating or not themselves. A cat straining in the litter box is an emergency: cat cannot pee. And a painful mouth is worth ruling out early: dental pain.
Common questions
Questions we are asked
When is a cat a senior?
Around eleven years is the usual dividing line, and cats are considered mature from about seven. What matters more than the label is that screening bloodwork starts before there is a symptom, because that is what makes kidney and thyroid disease manageable.
How often should a senior cat be checked?
Every six months for a wellness examination and screening, with more frequent rechecks when medically indicated. Regular check-ups let us detect problems early, before they become expensive or painful.
My cat hates the carrier. Is it worth the stress?
Yes, and we can reduce it. Call (714) 274-9305 before your visit and we will talk through what to expect and how to make the trip easier — that conversation is part of what Cat Friendly certification is about.
