How to Keep Your Cat Cool in a UK Heatwave — Summer Guide

UK summers are getting hotter. July 2026 saw temperatures hit 33°C in parts of southern England, and for cat owners that means one thing: helping your feline friend cope with heat they are not built for. Unlike dogs, cats evolved in hot, arid climates — but the domestic cat's ability to handle British heatwaves has limits. Their bodies are designed to conserve heat, not shed it, which makes sudden hot spells genuinely dangerous.

Here is the good news: keeping your cat cool through a UK heatwave does not need expensive gadgets or major home changes. A few smart purchases and some daily habit tweaks make all the difference between a miserable, overheated cat and one that barely notices the temperature outside. This guide covers everything from cooling products that actually work to the early warning signs of heatstroke that every UK cat owner should know.

Why Cats Struggle With Heat

Cats are masters of comfort-seeking, but biologically they are not great at cooling down. They have sweat glands only in their paw pads, and their main cooling mechanism is grooming — saliva evaporating from their fur provides a small cooling effect. Panting is a last resort, not a normal cooling method like it is for dogs. When a cat starts panting, they are already overheated.

A cat's normal body temperature sits between 38°C and 39°C. Once ambient temperature approaches or exceeds that, they cannot passively shed heat. Add thick fur, a tendency to find sunny spots, and no instinct to drink more water when it's hot, and you have a recipe for heat stress.

This is especially true for certain types of cats:

• Flat-faced breeds (Persians, Exotics, British Shorthairs) — their shortened airways make panting and heat exchange less effective
• Senior cats (10+ years) — their bodies regulate temperature less efficiently
• Overweight cats — extra fat acts as insulation, trapping heat inside
• Kittens — their temperature regulation is still developing
• Long-haired breeds — thick coats trap heat close to the body

Cooling Mats and Beds — Giving Your Cat a Cool Zone

The single most effective product for helping a cat through a heatwave is a cooling mat or bed. These use one of two technologies: self-cooling gel that absorbs body heat and dissipates it, or pressure-activated gel that stays cool until your cat sits on it. Unlike a damp towel (which warms up fast and gets soggy), a proper cooling mat stays cool for hours.

For cats that prefer a more bed-like surface, the CATISM Cooling Cat Bed combines a cooling base with raised cushioned edges. Cats love having their head propped up, and the airflow underneath the bed helps keep them cooler than a flat mat on the floor would. The cover removes for machine washing, which matters when your cat drags in garden heat and dust.

If budget is tight, the ADEPTNA Self-Cooling Gel Mat costs under 12 quid and works on the same gel principle. You can fold it up when not in use, which makes it handy for hot-weather vet visits or trips to the cattery.

Where to place cooling mats: Cats choose their cool spots based on air movement, not just surface temperature. Put the mat on tiles or wood flooring (not carpet), near an open window or a shady corner. Avoid putting it in direct sun — that defeats the purpose entirely. If your cat ignores the mat initially, try putting a favourite toy or some catnip on it to encourage investigation.

Hydration — Getting Your Cat to Drink More

Cats evolved from desert-dwelling ancestors and have a naturally low thirst drive. In hot weather, this works against them. A cat that would normally get most of their water from food (wet food is about 78% water) needs additional encouragement to drink during a heatwave.

Water Fountains Make a Real Difference

Most cats prefer running water to still. It triggers their instinct that flowing water is fresher and safer than standing water. A cat water fountain can double or triple your cat's daily water intake, and every vet agrees that makes a real difference during hot weather.

A step up is the Advanced 304 Stainless Steel Fountain with a 2.2-litre capacity that can last up to two weeks between refills for a single cat. Its multi-stage filtration catches hair, dust, and impurities — useful if your cat is fussy about water taste. The Ultra-Quiet 2.2L Fountain is another solid option at a similar price point, with a visible water level window so you never run dry by accident.

Smart Hydration Tricks

• Add ice cubes to water bowls — many cats enjoy batting them around, which also keeps the water cool longer
• Switch to wet food during hot days, or add warm water to dry kibble to create a gravy
• Lickable treats are effectively hydration in a tube — they contain mostly water and many cats find them irresistible
• Place multiple water stations around the house, not just next to food bowls (many cats prefer drinking away from where they eat)

For hydration treats, Webbox Lick-e-Lix variety packs are a UK favourite — creamy, high-moisture treats that act like a hydration boost in a tube. The Dreamies Creamy Treats are another option that most cats go mad for. A LickiMat smeared with wet food or yoghurt and frozen for an hour makes a great cooling enrichment activity.

Summer Grooming — Help Your Cat Shed Their Winter Coat

Cats shed their winter undercoat naturally as temperatures rise, but they need help getting rid of loose fur. A cat carrying a thick winter coat into August is going to overheat faster than one that is well-groomed. Daily brushing during summer removes loose fur that would otherwise trap heat against the skin.

Regular grooming also prevents fur matting, which creates warm, damp patches against the skin that can lead to skin infections. A stainless steel comb or a grooming glove works well for short-haired cats; a wider-toothed comb or de-matting tool is better for long-haired breeds like Persians and Maine Coons.

Important: Never shave your cat in summer. A cat's coat provides insulation against both cold AND heat. It also protects against sunburn. Shaving removes that protection and can lead to overheating (because the cooling mechanism of grooming relies on having fur to wet with saliva) and sun damage. A thorough brush-out is all they need.

Setting Up Your Home for a Cool Cat

You do not need to keep the house at 18°C to keep your cat comfortable. Small adjustments to your home environment make a big difference.

Create Airflow

Cats are experts at finding breezes. Open windows on opposite sides of the house to create through-drafts. If you have a window that gets direct afternoon sun, close the curtains or blinds on that side while keeping other windows open. A fan placed on the floor (not pointing directly at your cat, but circulating air nearby) helps. Some cats enjoy sitting in front of a fan — let them choose the distance.

Provide Cool Floor Surfaces

Tile floors, stone hearths, and shaded concrete stay significantly cooler than carpet or wood. If your cat has favourite cool floor spots, do not cover them with rugs during summer. A tile in the bathroom or a shaded corner of the kitchen is a natural cooling station.

Keep Sunbathing Under Control

Cats love a warm patch of sunlight, but on a 30°C day, a sunbeam on carpet can hit 40°C+ quickly. Gently move your cat if they fall asleep in direct sun during the hottest part of the day (12-4pm). Give them an equally appealing spot in the shade with a cooling mat.

Fresh Water Everywhere

Put water bowls in multiple rooms, not just the kitchen. Stainless steel or ceramic bowls stay cooler than plastic. Change the water twice a day during hot weather — warm, stale water is unappealing and can grow bacteria faster.

How to Spot Heatstroke in Cats — and What to Do

Heatstroke in cats is a genuine emergency. Unlike dogs, cats do not usually collapse from heat in public because they hide when they feel unwell. By the time you notice something is wrong, they may already be in serious trouble.

Early Warning Signs

• Panting or breathing with an open mouth (cats rarely pant — this is a red flag)
• Drooling or excessive salivation
• Restlessness, pacing, or agitation
• Bright red gums and tongue
• Warm ears and paw pads to the touch
• Vomiting or diarrhoea

Advanced Signs (Emergency)

• Stumbling, wobbling, or loss of coordination
• Lethargy and collapse
• Seizures
• Unconsciousness

What to Do If You Suspect Heatstroke

1. Move your cat to a cool area immediately — shade, tiled bathroom, or an air-conditioned room if you have one
2. Apply cool (not cold) water to their paws, ears, and belly. Do not use ice water — rapid cooling can cause shock. Lukewarm water that feels cool to your wrist is about right
3. Offer small amounts of water — do not force them to drink. If they will not drink, wet their gums with a damp finger
4. Contact your vet immediately — even if your cat seems to recover, internal damage from overheating can take hours to show

Wrap your cat loosely in a damp towel for the journey to the vet, and keep the car ventilated. Do not cover their head or restrict their breathing.
