Overview
Despite their desert origins and well-known love of sunbathing, too much heat can be dangerous for cats. Like dogs and humans, heat stroke in cats develops when their body temperature rises too high and they can’t cool down quickly enough. Kittens, older cats, overweight cats, flat-faced breeds like Persians, and those with health conditions are most at risk. Even a warm day can be hazardous if your cat is trapped in a greenhouse, shed, or sunny room without ventilation.
Signs of heat stroke in cats include panting, drooling, red gums, vomiting, or collapse. If not treated quickly, it can lead to seizures, organ failure, or death. The good news is it’s often preventable. Simple steps like providing fresh water, shaded spots, cooling mats, or frozen treats can help keep your cat safe, comfortable and cool all summer long.
