July 13, 2026
As temperatures rise this month in North London, keeping your cat hydrated is especially important, as pets can lose fluids quickly.
At Elizavet, many owners ask us how to tell if their cat is drinking enough. That’s why our veterinary team in Maida Vale have put together practical advice to help you recognise when your cat needs more water so you can keep them hydrated this summer.

Do cats need more water in summer?
Yes – cats lose more fluid through panting, grooming and activity due to the heat. Not to mention most cats love of a good long sunbathe when the weather allows.
Our veterinary team in Maida Vale explain that cats lose heat more passively through their skin and fur, their breathing, and the surrounding air – especially when it’s cool or moving. Some cats will naturally drink more, but others may not, which is why monitoring intake is important.
Diet also plays a role. Cats fed mainly dry food will generally need to drink more compared to those eating wet food or fresh produce, because dry diets contain very little moisture.
As a general guide, many cats will regulate their own intake if fresh water is always available. However, there are some useful ways to help.
How to keep your cat hydrated in summer
These simple steps from Elizavet can help maintain good pet hydration in summer, with a few small adjustments depending on your pet:
Provide constant access to water
Water should always be available. In the North London hot weather, pets may drink little and often, so even short periods without access can increase the risk of dehydration.
Change water regularly
Changing water frequently helps keep it clean, cool and free from debris. Your cat is unlikely to be as interested in stale water, so regular refreshing can encourage better drinking habits.
Offer multiple water sources around the home
Placing more than one bowl in different areas encourages drinking. Cats may be more likely to drink if water is nearby where they rest.
Keep water in cool, shaded areas
Positioning water sources in shaded areas is always useful to keep the water cool. It’s particularly important to ensure that food and water bowls are placed in separate areas too.
Add wet food where appropriate
Incorporating moisture through diet can support hydration. Wet food contains a high percentage of water anyway but adding a small amount of extra water or pet-safe broth to dry or wet food is of the most effective methods of improving your cat’s hydration.
When should I be concerned?
While some variation in drinking is normal, if your cat is not drinking, seems unwell, or shows changes in behaviour, it’s best to seek advice promptly.
