Prada and the hot season, what helps

Prada is a big boy with a lot of fur and Chiang Mai in April is brutal. Last year he was panting on the balcony every afternoon and I got scared he would get heatstroke. Now the routine is: aircon at 26 in the bedroom, a fan pointed at the floor so the cool air spreads, and a cooling mat I bought online. There is a wet towel on the bathroom tiles too, he lies on it like a pancake. No walks after 10am. We go out at 6 when the air is still ok. Brushing matters too. I brush him every week to get the loose undercoat out, otherwise it is like a sweater he cannot take off. I don't shave him, the vet said his coat protects his skin from the sun as well, so I just do the belly and the back of the legs. Lamyai sits in the sun all day and doesn't care lol. Different cat, different plan.
