A California woman has melted hearts on social media after showing the sweet gesture her mother made to their neighborhood's strays.

On June 9, user @laa_colombianacx5 posted a video on TikTok, writing in overlay text: "My mom takes care of stray kitties outside and she bought them this portable AC. He never leaves our house now."

The clip, which has received 3 million views and more than 486,400 likes on the platform, shows a stray tabby cat lying by the poster's door, soaking in fresh air from the portable air conditioning her mom bought for him. The cat then moves to the scratch post she left outside for him.

"We wish we could bring all of them inside but we have 4 cats already," the poster wrote in the video's caption. Newsweek contacted @laa_colombianacx5 for comment via TikTok. We could not verify the details of the case.

Thousands of viewers have commented on the video, with one writing, "The way he started using the scratcher for you. He LOVES you girl."

"My mum started with 2 cats, and now we have 14 cats at home," another user added. "She just can't resist helping stray cats."

A commenter wrote: "I can tell She takes amazing care of them because they're ear tipped. Please thank her. Also that one looks dehydrated (when they stop cleaning fur and it's hot. No more saliva in tongue)."

Cats usually love taking naps in warm places, but too much heat is not good for them. Because they're unable to sweat, cats can overheat in hot weather, potentially causing heat exhaustion or even heatstroke, which can be fatal for them.

So how do you know how hot is too hot for your cat? Bond Vet, a veterinary clinic, said a good rule of thumb is that if you feel hot, your cat probably feels hot, too.

"The exact temperature tolerance may vary from cat to cat, depending on their lifestyle and other factors. Humidity may also contribute to overheating," the company said on its website, adding that older, overweight or short-nosed cats are much less heat tolerant than other kitties, so they can overheat more quickly.

Bond Vet said, "When they start to get too warm, pets may first experience heat exhaustion, which is when they slow down or become lethargic in an attempt to reduce their body temperature."
