Everyone, this is Ralphee the kitty. She was rescued from a barn and has a neurological disorder called cerebellar hypoplasia (CH), which occurs when the part of their brain that controls motor skills and coordination is underdeveloped.
"These cats are known for their 'drunken sailor' walk, which is why they're known endearingly as 'wobbly cats.' Unless a CH cat has other health issues, their life expectancy is the same as a cat's without CH."
When Ralphee was rescued, she met Max the cattle dog and the two became instant friends.
"Ever since Ralphee was brought home, Max is never far away," the video's description says. "He appears to be forever curious and watches over Ralphee wherever she goes…[And] she will often get excited when he is nearby and leap in the air before playfully charging in his direction."
