A 6-year-old rescue pit bull has broken set notions of animal parenthood by actually adopting a tiny kitten and treating it like its own kid. Bubba, who was himself adopted at the tender age of three months, immediately clicked with the cute ginger kitten from a shelter, according to his owner Rebecca Pizzello.Apparently the feelings of love are mutual in this case.Doesn’t Bubba look like the typical protective parent for little Rue over here? Rue likes spending most of her time with Bubba and seems to think that the adorable canine is her mother for real.Of course, like most babies with their parents, tiny Rue loves to shower her ”mom” with too many kisses. She enjoys posing with Mama Bubba even when the latter is fast asleep!Folks were totally spot on when they said that love knows no boundaries.
