The RSPCA has issued a warning for anyone with a garden shed, greenhouse, or summerhouse to check these structures before closing them, as cats can become trapped and suffer from heatstroke or dehydration. The animal welfare organization advises that cats often seek out warm spots in outbuildings, but if accidentally confined, they can face fatal consequences.
Why the Warning Matters
According to the RSPCA, temperatures inside sheds, greenhouses, and summerhouses can quickly rise to 47°C (117°F), which can be lethal for animals. The charity's website states: "Check sheds, greenhouses and summerhouses before closing them up. Cats can find their way into warm areas if they're looking for a cosy spot, but could get too hot or dehydrated if they get trapped."
The RSPCA also emphasizes never leaving animals in hot cars, conservatories, outbuildings, or caravans, even for a short time, due to the rapid temperature increase.
Hot Weather Advice for Cat Owners
The RSPCA provides additional guidance for cat owners during hot weather: "Where safe, keep windows and doors ajar to allow a breeze through the house. If your cat lives indoors full-time, consider different options such as windows with locking mechanisms, which allow air into the house while also keeping your cat indoors."
They also recommend ensuring cats have constant access to shade and fresh drinking water, and suggest adding ice cubes to water bowls or making ice cube treats to help keep them cool.
Heatstroke Risks in Cats
PDSA notes that while cats are unlikely to develop heatstroke from exercise, they are at risk when accidentally shut in warm places. Symptoms of heatstroke in cats include confusion, drooling, seizures, vomiting, panting, and low energy. Owners are advised to contact a vet immediately if they suspect their cat has heatstroke.
Certain cats are more vulnerable, including older cats, young kittens, obese cats, and those with heart disease. The advice is particularly timely given the Met Office's extreme heat warnings for much of southern and central England and Wales, with red and amber warnings in place.
Ongoing Heat Warnings
The Met Office has issued an extreme heat warning covering much of England and Wales, with red warnings in effect from Wednesday morning through Thursday night, embedded within a wider amber warning area. The RSPCA urges vigilance during this period to protect pets from heat-related dangers.
