How to detect the first signs of kidney failure in cats and dogs?

The renal insufficiency in cats and dogs is a common disease, especially in older animals. It often progresses silently, which makes it difficult to identify early. This article helps you recognise the first signs of renal insufficiency in cats and dogs, understand the causes and quickly adopt the right reflexes to protect your companion's health.

Understanding and identifying renal insufficiency

Why is renal insufficiency so important to detect in dogs and cats?

Renal insufficiency in cats and dogs is a serious condition that requires particular attention. Owners must be alert to the signs and symptoms that could indicate kidney problems.

The kidneys play an essential role: filtering toxins, regulating water in the body, balancing minerals and producing certain hormones. When their function declines, waste accumulates and the body gradually becomes poisoned. Renal insufficiency in cats and dogs is one of the leading causes of death in senior cats. In dogs, it can progress very quickly if it is not managed.

Renal insufficiency in cats and dogs is often linked to more serious diseases, so it is crucial to monitor your pets' health.

Renal insufficiency in cats and dogs can often be managed with an early diagnosis and appropriate treatment.

It is crucial to diagnose renal insufficiency in cats and dogs as soon as the first signs appear, to avoid serious complications.

Causes and symptoms to watch for

Common causes:

• Natural ageing
• Repeated urinary infections
• Congenital diseases (more common in certain breeds)
• Poisoning (plants, medication, household products)
• A diet too rich in minerals

First warning signs:

• Increased thirst (polydipsia)
• More frequent urges to urinate, or on the contrary rarer ones
• Weight loss despite a normal appetite

👉 If any of these signs appear, it is advisable to consult a vet quickly to carry out a blood test and a urine analysis.
