Common Chronic Cat Conditions
As our feline companions age, they often become masters at hiding signs of illness. While many owners expect their cats to slow down as they get older, subtle changes in behaviour, appetite, mobility or drinking habits can sometimes indicate an underlying health condition.
Understanding the signs of common chronic illnesses can help you seek veterinary advice sooner and ensure your cat receives the support they need to enjoy a happy and comfortable life.
In this guide, we'll explore four of the most common chronic conditions affecting cats:
- Hyperthyroidism
- Chronic Kidney Disease (CKD)
- Arthritis
- Inflammatory Bowel Disease (IBD)
Hyperthyroidism in Cats
Hyperthyroidism is one of the most commonly diagnosed conditions in older cats. It occurs when the thyroid gland produces excessive amounts of thyroid hormone, causing the body's metabolism to speed up.
Common Signs of Hyperthyroidism
- Increased appetite
- Weight loss despite eating well
- Increased thirst
- Increased urination
- Hyperactivity or restlessness
- Poor coat condition
- Vomiting
Many owners are surprised to learn that a cat who appears hungrier than ever may actually be unwell.
If you notice these signs, it's important to speak with your veterinary practice.
Supporting Your Cat at Home
Monitoring changes in weight, appetite and drinking habits can help identify concerns early.

- Cat feeding accessories
- Water fountains

Chronic Kidney Disease (CKD) in Cats
Chronic Kidney Disease is another common condition affecting senior cats.
The kidneys play a vital role in filtering waste products from the bloodstream and maintaining hydration. As kidney function declines, cats may begin to show subtle signs that can easily be mistaken for normal ageing.
Signs of CKD
- Drinking more water
- Increased urination
- Weight loss
- Reduced appetite
- Lethargy
- Poor coat quality
Because CKD develops gradually, regular monitoring is extremely important.
Supporting Hydration
Encouraging water intake is often beneficial for senior cats.
Many owners find the following products useful:
- Cat water fountains
- Feeding and hydration accessories
- Raised feeding stations
Arthritis in Cats
Many people associate arthritis with dogs, but it is also extremely common in cats, particularly those over 10 years of age.
The challenge is that cats rarely show obvious signs of pain. Instead, they adapt their behaviour to avoid discomfort.
Signs of Arthritis
- Sleeping more than usual
- Reluctance to jump
- Difficulty using stairs
- Reduced grooming
- Less interest in play
- Changes in temperament
How to Make Life Easier
Small adjustments around the home can make a big difference.
Consider:
- Providing ramps or steps
- Using low-entry litter trays
- Offering warm, supportive bedding
- Keeping food and water easily accessible
Joint Support for Cats
Many owners choose to support mobility with:
- Joint support supplements
- Omega-3 supplements
- Orthopaedic bedding

Inflammatory Bowel Disease (IBD) in Cats
Digestive issues can become more common as cats age.
Inflammatory Bowel Disease (IBD) affects the digestive tract and can cause ongoing gastrointestinal symptoms.
Signs of IBD
- Frequent vomiting
- Diarrhoea
- Weight loss
- Reduced appetite
- Changes in stool consistency
While occasional digestive upset can happen, persistent symptoms should always be discussed with your vet.
Supporting Digestive Health
Many cat owners find it helpful to focus on digestive wellbeing through:
- Consistent feeding routines
- Gradual dietary changes
- Monitoring appetite and weight
- Digestive support products
Products That May Help Support Digestive Health
- Probiotic supplements
- Digestive support products
- Feeding accessories
Why Monitoring Your Cat's Health Matters
One of the most important things any cat owner can do is monitor changes over time.
Pay particular attention to:
- Weight
- Appetite
- Water intake
- Mobility
- Grooming habits
- Litter tray use
- Behaviour
Small changes can often provide valuable clues about your cat's health and may help identify problems before they become more serious.
