There's just something so sweet about unusual sets of animal friends. Take Bubba and Rue, for instance. Pit Bull Bubba needed a new friend, and his human totally came through for him, in the form of a tiny baby kitten named Rue. This New York duo look like two peas in a pod, despite their size, age, and breed differences. We may or may not have squealed a teeny bit at the video of Bubba affectionately licking Rue's little head. I mean, does it get any cuter? Scroll through to see some of their best Instagram snaps, and be sure to add them to your Instagram feed for an extra dose of cute!
