Common Health Conditions in Older Cats
Older cats are very good at masking illness. It's an evolutionary survival strategy that served wildcats well in environments where appearing weak attracted predators. In a domestic setting it means that significant health conditions can progress substantially before owners notice anything is wrong. Regular veterinary monitoring is essential for senior cats for exactly this reason.
Chronic Kidney Disease
The most common serious health condition in cats over 10 years of age. The kidneys gradually lose their ability to filter waste from the blood, and uraemic toxins accumulate. Early signs are subtle: slightly increased thirst and urination, mild weight loss. Later signs include vomiting, reduced appetite, lethargy, and poor coat quality. CKD is not curable, but it is very manageable, and cats diagnosed early can live years in good quality of life with appropriate management.
The gut microbiome is directly relevant to CKD: bacteria in the large intestine produce uraemic toxins including indoxyl sulphate that worsen kidney disease. Reducing the microbial production of these toxins through gut microbiome support is an emerging and evidence-backed component of CKD management.
Hyperthyroidism
The most common hormonal condition in senior cats. A benign tumour of the thyroid gland causes overproduction of thyroid hormone, speeding up the metabolism. Signs include weight loss despite a ravenous appetite, increased thirst, vomiting, diarrhoea, restlessness, and a racing heart. Easily diagnosed with a blood test and manageable with medication, radioactive iodine, or surgery. Untreated, it progresses to heart failure and kidney failure.
Dental Disease
Periodontal disease affects the majority of cats over 5 years and its severity typically increases with age. Dental pain in cats is frequently missed because cats rarely show obvious pain signals. Signs include reduced food intake, preference for softer food, drooling, pawing at the mouth, and bad breath. Regular dental assessments and professional cleaning under anaesthesia as needed are part of responsible senior cat care. Dental disease creates a chronic source of systemic bacterial and inflammatory load that affects the gut microbiome and contributes to systemic disease.
Arthritis
Feline arthritis is massively underdiagnosed. Studies using radiography in cats over 12 years find arthritis in close to 90% of them, yet very few are diagnosed or treated. Signs include reduced jumping height, reluctance to use the litter tray if it has high sides, reduced grooming of the back and base of the tail, and subtle behavioural changes like increased irritability when handled. NSAIDs for cats are available from vets and can make a remarkable difference to quality of life.
Cognitive Dysfunction
Feline cognitive dysfunction, the cat equivalent of dementia, is estimated to affect over a third of cats aged 11 to 14 years and over half of cats over 15. Signs include vocalisation particularly at night, disorientation, reduced interaction, changes in litter tray habits, and disrupted sleep patterns. The gut-brain axis is relevant: gut-driven neuroinflammation contributes to cognitive decline, and gut microbiome support is a meaningful complement to veterinary management.
Diabetes
Feline diabetes is more common in overweight male cats and senior cats generally. Signs include increased thirst and urination, weight loss despite eating well, and hind limb weakness in advanced cases. Managed with insulin and diet. The gut microbiome influences insulin sensitivity and glucose metabolism and gut health support is relevant to diabetic cats alongside their primary management.
Ipromea for Senior Cats
Tummy Time Liquid Probiotics for Dogs and Cats (500ml)
Daily probiotic and Zoonatant postbiotic support in liquid format. Safe alongside all medications commonly used in senior cats including those for CKD, hyperthyroidism, arthritis, and diabetes. Pour over food once daily. The liquid format works well for senior cats who have developed preferences and aversions to food texture and smell.

Collagen Rich Bone, Skin & Coat Care
Poor coat quality is one of the most consistent early signs of declining health in senior cats, appearing well before many conditions reach clinical significance. Declining collagen production, reduced protein absorption, and omega fatty acid deficiency all converge to produce the coarser, thinner, less lustrous coat common in older cats. Ipromea's Collagen Rich formula addresses all three: bioavailable collagen peptides restore skin structure, marine-sourced omega-3s reduce skin inflammation and improve coat texture, and the targeted micronutrient profile supports the follicle health that produces a denser, healthier coat. Suitable for dogs and cats. Safe alongside all senior cat medications.

Cat Stress & Anxiety Support (60g)
Cognitive dysfunction, chronic pain from undiagnosed arthritis, sensory decline, and the disrupted sleep patterns that come with age all elevate anxiety in older cats. Ipromea's Cat Stress and Anxiety Support combines ashwagandha, L-theanine, and Zoonatant postbiotic technology to reduce cortisol-driven reactivity and promote a calmer baseline state without sedation. Particularly useful for senior cats with night-time vocalisation, restlessness, or disrupted routines associated with cognitive decline.

Frequently Asked Questions
How often should my senior cat see a vet?
Twice yearly with blood and urine panels is the standard recommendation for cats over 10 years. Many of the most common senior cat conditions, kidney disease and hyperthyroidism in particular, are identified through blood testing before clinical signs are obvious and are much more manageable when caught early.
My older cat is losing weight but still eating. Should I be worried?
Yes. Weight loss despite eating in an older cat is a classic presentation of hyperthyroidism, diabetes, or advanced kidney disease. It can also indicate cancer or malabsorption from gut dysfunction. A vet visit with blood and urine testing is appropriate without delay.
Can gut health support help a cat with kidney disease?
The emerging evidence supports gut microbiome modification as a complement to CKD management in cats. Beneficial gut bacteria reduce the production of uraemic toxins that drive disease progression. Daily probiotic and postbiotic supplementation alongside appropriate diet and veterinary management is a rational and evidence-informed approach.
