One special little boy from Brazil decided to take matters into his own hands when he visited a litter of kittens at his friend’s house and noticed that one of them couldn’t walk.

Nine-year-old João felt terrible for the kitten, who was unable to play with her siblings. He returned home eager to devise a solution to the feline’s mobility challenges.

Using some materials given to him by a friend, João set to work on a custom wheelchair, tailored specifically to the kitten’s small frame.

Sure enough, the adorable kitten was moving around in no time after being introduced to her wheelchair, and it was all caught on camera and featured in a Facebook post by his proud mom.

João’s kind and selfless act demonstrates his impressive creativity, big heart, and wisdom beyond his years.
