The Japanese kitten - named Wasabi-chan - was saved by her owner after she was found seriously injured on the street following a crow attack.
"She was attacked by a crow," explained Reddit user DopeSk1llz. "Her top jaw was fractured, a hole in her throat, tongue was ripped, and part of [her] gum was eaten."
The mushroom outfit is used by Wasabi-chan's owner to hold her down while feeding her with a tube.
"The rescuer was feeding her with a tube which Wasabi-chan hates, thus this crochet straitjacket to hold her down while feeding," Dopesk1llz continued.
"She's gaining lots of weight and is now looking adorable!"
Wasabi-chan's recovery can be followed by visiting her owner's Twitter account.
