UK households with indoor cats are being warned about the risk of potentially fatal falls during hot weather, just as the fifth heatwave of the summer is set to arrive. Animal charities Cats Protection and the Blue Cross have issued the alert, noting that cases of “high-rise syndrome” – where cats suffer injuries from falling from heights – tend to spike in summer as indoor cats are tempted outside by warmer temperatures, birds, and movement.
Charities report 33 cats treated for fall injuries
Blue Cross animal hospitals in London and Grimsby have already treated 33 cats this year for injuries from falls. The charities are advising pet owners not to leave windows and balconies open and unattended.
“It is true that cats can twist in mid-air, but it is not always the case that they will land safely,” said Izzy Hocking, a veterinary engagement manager at Cats Protection. “You might think that cats naturally understand the dangers of heights, but this is not always true. Cats living in flats, particularly those who have never experienced the outdoors, do not recognise the risks posed by open windows, doors or balconies.”
Severe injuries and fatalities possible
Hocking added: “Depending on the height it falls from, a cat could suffer severe injuries such as broken limbs, jaw fractures and internal trauma including brain damage. In some cases, falls can prove fatal or result in euthanasia due to the severity of injuries.”
The warning comes as the UK braces for blistering heatwave conditions to return next week, with a high of 36C expected in parts of East Anglia and south-east England by Thursday. With people likely to open windows and doors to balconies, the charities have warned that younger and more curious indoor cats, especially unneutered males, may be particularly at risk as they are more tempted to roam outside.
Cat owner's story highlights the danger
Alliah Seed’s three-month-old kitten Sapphire was “very lucky” to only suffer a fractured toe after falling from the window ledge of a fifth-storey flat. Ms Seed took Sapphire to the Blue Cross animal hospital in Victoria, central London, fearing the worst because her pet had collapsed with dried blood around her nostrils.
“Sapphire has been used to resting on the windowsill and getting fresh air with no problems until now,” Ms Seed said. “I was totally shocked when she fell, she must have been spooked or something.”
Preventive measures recommended
Blue Cross and Cats Protection advised owners of indoor cats to fit secure netting or screens over windows, doors, and balconies to reduce the risk of falls. Open windows should not be left unattended, especially overnight, and cats should be neutered to reduce roaming behaviours. Indoor enrichment such as toys, cat trees, walkways, and shelves can also help prevent an indoor cat from wanting to go outside by keeping them entertained and active.
“I’m soon moving to a ground floor flat but I will still put up mesh to prevent her from falling or jumping outside again,” Ms Seed said. “Cat owners living in blocks of flats really should do the same to prevent terrible and potentially tragic accidents.”
Roisin Bolger, veterinary standards lead at Blue Cross, said: “Even from a relatively low storey, cats may break several bones or land somewhere dangerous like a spiked railing or on to dangerous objects below. Injuries will often need extensive surgery and a lengthy stay in hospital. Cat owners really must take measures to prevent their pet from falling from a window or balcony to prevent suffering or death.”
