According to various comments on shimejiwasabi's Instagram account, this little kitty has a mouth injury that required her to have a feeding tube. And because little kittens are a wiggly type, her owner created these knit outfits to limit her movement during feeding time & creating an adorable set of Instagram "OMG is this cute!" photos for your viewing pleasure. 

It's cute and adorable and probably THE cutest thing you will see all day!
