Summers keep getting hotter, and it's not just us who notice. According to the Deutscher Wetterdienst, 2024 was the warmest year since records began, with an average of 12.5 days above 30 degrees Celsius. For dogs and cats, that's more dangerous than for us: they barely sweat and regulate their body temperature almost entirely through panting.

At the same time, you're only human. Between work, family and errands, it's impossible to keep an eye on the water bowl all day long. That's exactly where an automatic water fountain closes the gap: fresh, filtered, circulating water around the clock that invites pets to drink.

Research shows why this matters: around 80% of all heat-related illnesses in dogs occur during the summer months, and chronic kidney disease affects 30 to 40% of all cats over the age of ten, often made worse by insufficient water intake.

Because dogs and cats can barely release body heat through their skin. They have almost no sweat glands and cool down mainly by panting and through their paws. On hot days, that quickly stops being enough, and body temperature rises to a critical level.

The numbers speak for themselves. A UK study attributed around 80% of all heat-related illnesses in dogs to the summer months, with a mortality rate of around 14%, roughly one in seven severely affected animals. During the 2022 heatwaves, that share rose to around a quarter.

It's not just the hot car that's the problem: in a British Veterinary Association survey, 38% of vets had seen a dog suffer heatstroke after a walk on a hot day.

And the danger doesn't end with heatstroke. Insufficient water intake places a long-term strain on the kidneys, especially in cats. In cats over 15, up to 80% suffer from chronic kidney disease. Constant access to fresh water is therefore not a minor detail, it's health prevention.

Nobody can keep an eye on the water bowl all day. You're at work, out and about, or simply busy, and standing water quickly turns warm, dusty and unappealing in the heat. Many pets then simply drink too little, right when they need fluids the most.

An automatic water fountain keeps the water moving, filters out hair and debris, and keeps it cool and fresh. Flowing water also awakens the natural instinct to drink: in a pilot study, cats drank more on average from a flowing source than from standing water.

The research is mixed, not every cat automatically drinks more. But pets with a preference for flowing water benefit noticeably, and clean, cool water is a win for any pet in the height of summer.

Then there's the design. All PETLIBRO fountains are deliberately built low with a shallow drinking area. That way, cats don't have to squeeze their sensitive whiskers into a narrow bowl, a common reason why they refuse to drink. Less irritation of the whiskers means more relaxed, more frequent drinking.

In short: it depends on your pet, household size and budget. Four models cover it all, from a compact entry-level option for one cat to a smart fountain with app and RFID recognition for multiple pets. All quiet and low-built. Here's the direct comparison by price and features.

A water fountain is the foundation, but a few simple habits make a real difference. Avoid walks in the midday sun, since exercise is the most common trigger for heatstroke, responsible for around half of all cases in studies. Instead, go out early in the morning or late in the evening.

Provide shade and cool spots to retreat to, never leave pets in the car, and place several water sources around the house. For cats, wet food also helps, as it has a high moisture content and supports daily water intake.
