How Hot is too Hot for Cats in Summer?

  • 9 min read
Our house cats are the descendants of steppe inhabitants; However, they do not tolerate such heat as well as their ancestors. The often extreme weather conditions of the recent past with periods of sudden, high temperatures are also causing problems for cats. Read here how you can make life more pleasant for your cat on particularly hot days.

What Temperature Is Too Hot for Cats?

Any temperature over 100 F or 38 C is too hot for cats. Despite their fondness for all things warm, it’s possible for cats to become overheated. To cool off, they may seek out cool places like a bathtub or sink, and some cats may stick their faces in front of an air conditioning vent to catch the cold breeze. Cats don’t often suffer from heatstroke, but it can happen. If your cat shows signs of being overheated, including sweating, take steps to cool them off, including offering them plenty of cool, fresh water. If your cat’s body temperature is higher than 104 F, it can be a sign of heatstroke or illness, so contact your veterinarian right away.

How do cats cope with high temperatures?

Every cat lover knows the picture when the velvet paw lounges in the sun. Cats love sunshine and take the opportunity to let their fur warm. However, excessive heat is unpleasant for the cats because the animals can only sweat to a very limited extent. They only have a few sweat glands, which primarily serve to send scent signals and not to regulate body temperature. To protect themselves from overheating, cats try to cool themselves by panting. In addition, they exploit the effect of evaporation cooling: By grooming themselves particularly intensively in summer, the animals moisten their fur with saliva. They also try to avoid any unnecessary movement. If it’s really hot outside, the animals become lethargic and move noticeably less.

How can I help in extreme heat?

When the outside temperatures are very high, cats with lush fur in particular suffer from the heat. Long-haired cats therefore shed more hair in summer. Daily brushing will help your cat get rid of excess fur. You can also ensure cooling through the skin: rub the velvet paw with a slightly damp cloth. Outdoor cats independently seek out places in the shade on hot days. An indoor cat has it a little more difficult. It is ideal if you can offer your cat a secure balcony that also has shady places. The animal feels particularly comfortable between tempting catnip or cat grass. Be careful with other plants: many common ornamental plants are poisonous to cats and other pets. Many indoor cats also like to retreat to the bathroom or other rooms with cool floor tiles on hot days. Some cats enjoy settling into sinks or shower trays. Do not close the doors so that the animal always has free access to such a place.

If possible, you should try not to let the living space overheat in the first place. Ventilate well in the morning and evening and provide shade during the day with blinds or curtains. You can secure windows and balconies with cat protection nets. Such a cat net should have a mesh diameter of a maximum of three centimeters. If you add more stitches there is a risk of tangling. Caution is also advised when using fans. Aside from the risk of injury to curious cats, the constant cold draft can cause conjunctivitis and colds. Sunlight itself is also not without risk: light-colored and short-haired cats are at risk of sunburn, just like humans. Unscented baby sunscreen applied to the bridge of the nose and ears helps prevent this. Despite all these precautions, heat stroke is still the biggest danger a cat faces in the summer heat. Symptoms that indicate heat stroke include restless behavior, a body temperature of over 39°C, dark red gums, apathetic lying on your stomach and heavy panting. In such cases, the cat must be taken to the vet immediately!

Which food is best for summer?

On hot days, it is advisable to offer the cat more wet  food  to support its fluid intake. However, cats need less food overall than usual during a heat wave because their calorie expenditure is lower given the reduced physical activity. Our veterinarians from Dr. will be happy to help you with your cat’s individual diet. In an online consultation via video chat, the doctors will give you well-founded recommendations for suitable cat food and useful tips on feeding. You should offer the cat food in several small portions throughout the day and put away any leftovers immediately. Leftover food spoils quickly and attracts flies. When it’s hot, you shouldn’t offer food and water cold in the refrigerator: this can lead to stomach irritation. Almost more important than a filled food bowl is that the cat takes in enough fluids. Distribute several keys around the house or apartment so that the cat has enough water. Some cats are reluctant to drink and you have to use tricks to encourage them to drink regularly. A sip of tuna infusion or unseasoned chicken broth in drinking water flavors the drink. Some cats prefer to drink from a drinking fountain  or dripping faucet. But you can also take advantage of the cat’s play instinct. An ice cube in the water bowl or a fishing game in which you throw treats into a shallow bowl filled with water ensures splashing fun and cooling down.

Help your cat drink more – drinking fountains

Does your cat hardly ever get excited about water? Does just a few drops from the garden hose make her grimace? With a few tricks and drinking fountains you can still encourage them to drink more. Because just like us humans, cats can’t drink enough – especially in summer!

Are parasites and insects more dangerous in summer?

Insects and arachnids such as ticks, fleas and mites also become active in the summer months. Check your outdoor animal regularly, remove parasites and apply spot-on repellents . Apart from that, common insects are also unpleasant in summer. However, do not use insecticides against ants etc. and use natural alternatives, as cats are very sensitive to insecticides. Fly screens help against insects in the apartment. This is also important because an insect bite can also be dangerous for the house cat – for example if it hunts a wasp and is stung in a sensitive area.
