Rescued Pit Bull Treats 'Little Sister' Kitten Like a Princess

— -- This may just be the sweetest animal match made in heaven.

Bubba the pit bull terrier absolutely adores his “little sister,” an orange tabby kitten named Rue.

Their owner, Becca Pizzello, says Bubba has always had a soft spot for cats.

“I rescued Bubba six years ago from a shelter in Phoenix, Arizona, when he was 3-months-old,” Pizzello, of Brooklyn, New York, told ABC News. “At the same time, my roommate had rescued a litter of kittens that had to be bottle fed until old enough for adoption. Since then, Bubba has had an endless affection for cats. Literally obsessed.”

When Pizzello made the cross-country move to New York, she decided Bubba would love a kitten of his own to help keep him company.

“I always knew he’d love having one of his own but I wanted to wait until we moved to New York City this year,” she said.

“After weeks of applying for any baby kitten available for adoption, I finally received a call from a rescue in Brooklyn," Pizzello recalled. "They had a litter of kittens that were 7-weeks-old and would be ready in a week. A week later I went to Brooklyn to pick up a baby kitten having absolutely no idea what they looked like. Rue stood out like no other and I took her home as fast as I could. She was the only orange baby.”

Bubba and Rue’s matching fur color was a complete coincidence, and Pizzello couldn’t be more thrilled about it.

“The fact that Bubba and Rue have identical coloring still blows my mind,” she said. “I am the luckiest!”

Bubba treats Rue like an absolute Princess, cuddling with her round the clock and even bathing her with kisses.

“They instantly connected and are now inseparable,” Pizzello explained. “I think Rue thinks Bubba is her mom and Bubba loves it. He baths her like a baby and snuggles close to her to make her comfortable. They will definitely be a fun duo to watch grow up together!”

Since Rue is still so tiny, Pizzello says it’s helpful to have Bubba around helping keep an eye on her.

“If I walk away somewhere [Bubba] always follows me," she said. "Now I will say ‘go watch your sister’ and he turns around and goes and watches where she is."

“They're so painfully cute. She follows Bubba around everywhere and is just starting to play. I don't know how I got so lucky with two perfect munchkins.”
