Your cat barely sweats — only through tiny paw pads. Its body dumps heat into whatever it lies on. The aircon, the fan, the open window: they cool you. They barely touch your cat. That is why it keeps hunting for a cooler spot all afternoon.

Its 38.5°C body heat soaks into any surface until it quits. Vets call it surface heat saturation:

• Gel mats — saturated in 30 minutes (and most cats reject the plasticky feel)
• Frozen towels — body temperature in 10 minutes
• The famous cold tiles — done by mid-afternoon
• Lowering the thermostat — changes nothing on the surface

The afternoon tour of the flat. Sleeping on the bathroom tiles. Flopping flat on the kitchen floor. 3 out of 4 indoor cats show these signs of chronic thermal stress, and owners call it personality.

Ask Luna's owner. British Shorthair, six years old, house at 23°C, fresh water, regular checkups. Two summers of 'normal' little signs. Then one ordinary afternoon: a heatstroke emergency. £1,900.

The FreshPaw mat uses conductive ice silk with a breathable mesh back: it keeps pulling heat away for hours and never turns into a warm patch. Activated by your cat's own body weight. No electricity. No gel to leak. No water. No noise (cats have strong opinions about noise). It lies down — that is the whole manual.

24 hours: calmer, less restless. 1 week: the afternoon tour of the flat stops. 2 weeks: your cat claims the mat and stays on it for hours.
