How to Tell if Your Cat is Dehydrated: Signs & Tests
It can be difficult to estimate how much water your cat drinks each day. Cats not drinking enough water risk serious health issues, including kidney damage. Sometimes, reduced water intake itself may signal an underlying health problem requiring timely veterinary attention.
The Dangers Associated with Cat Dehydration
Dehydration in cats can lead to severe complications, most notably kidney failure, which can be fatal. Cats with diabetes are at higher risk as they often drink less water, which worsens dehydration and complicates their condition.
Often, dehydration symptoms may go unnoticed until the cat’s health deteriorates significantly. If you suspect your cat isn’t drinking enough, it’s essential to take them to a vet promptly for diagnosis and treatment.
Common Causes of Dehydration in Cats
There are various reasons your cat might become dehydrated. Digestive disorders like diarrhoea are a primary cause, leading to rapid fluid loss. Prolonged diarrhoea, if untreated beyond a day, can cause severe dehydration.
Other causes include heatstroke, urinary infections, vomiting, and systemic illnesses. If your cat displays symptoms such as excessive drooling, frequent urination, or signs of heat stress, you should seek veterinary care without delay.
Cats Are Often Fussy Drinkers
Many cats prefer fresh, running water rather than stagnant water in bowls. They may favour drinking from a dripping tap or flowing water fountain, which encourages adequate hydration.
Cats generally require around 60 ml of water per kilogram of body weight daily, but this varies according to size, diet, and activity level. Cats fed dry kibble tend to drink more water, so always ensure fresh water is available to support their kidney health.
How to Check if Your Cat is Dehydrated: Simple At-Home Tests
The Skin Elasticity (Skin Turgor) Test
This test measures skin elasticity, a good indicator of hydration status:
- Gently take hold of the skin on your cat's shoulder blades.
- Pull the skin upward slightly, then release it carefully.
- In a well-hydrated cat, the skin should snap back immediately to its normal position.
- If the skin returns slowly or remains tented, this indicates dehydration; the slower it returns, the more severe the dehydration.
Gum Moisture and Colour Check
Examine your cat’s gums as follows:
- Lift your cat’s lip gently and look at the gums. Healthy gums are pink, moist, and slippery.
- If the gums are dry, pale, sticky or tacky and saliva appears thick or rope-like, it’s a concerning sign of dehydration.
- Press lightly on the gums to see if the pink colour returns quickly. If it stays pale or the refill is slow, dehydration may be present.
Other Signs to Watch For
Additional indications of dehydration include:
- Sunken or dull-looking eyes
- Low energy or lethargy beyond their normal behaviour
- Loss of appetite or vomiting
- Panting, which is unusual and signals distress or overheating in cats
- Reduced urination or fewer litter box visits
What To Do If Your Cat Is Dehydrated
If any of these signs or tests suggest dehydration, arrange a veterinary visit as soon as possible. Early diagnosis and treatment can prevent serious complications. Your vet may provide fluid therapy and investigate underlying conditions causing dehydration.
Ensuring your cat has constant access to clean, fresh water and encouraging water intake, possibly through wet food, are important preventive steps.
Conclusion
Dehydration is a serious health risk for cats, potentially leading to irreversible kidney damage and other complications. Regularly monitoring your cat’s water intake, checking for early signs of dehydration using the skin elasticity and gum checks, and seeking prompt veterinary care are key to keeping your feline friend healthy and hydrated.
Remember, responsible pet ownership includes vigilant care to prevent dehydration. If in doubt, never hesitate to consult your vet for expert advice and support.
