Are cats sensitive to heat and how can I ensure they stay cool during hot weather?

Yes, cats are sensitive to heat and can easily become overheated. To ensure they stay cool during hot weather, provide plenty of fresh water, keep them indoors during the hottest parts of the day, provide access to shaded areas, use fans or air conditioning, and avoid leaving them in hot cars or enclosed spaces. Brushing their fur regularly can also help regulate their body temperature.
