The Met Office has issued its first ever Red Extreme heat warning for Monday July 18 and Tuesday July 19, with temperatures of 40C forecast in the UK.
People are advised to stay safe by drinking water and staying indoors between 11am and 3pm where possible, but it's not just humans who will find the record temperatures uncomfortable and stressful over the coming days.
Hot weather can not only be uncomfortable for animals, but also dangerous. It's important to be aware of the signs of heatstroke and heat exhaustion.
