Pit bulls sometimes have a bad rep for being aggressive, but six-year-old Bubba is clearly a complete softie.
Bubba was rescued from an animal shelter in Arizona and now spends her days nurturing a teeny, tiny ginger kitten called Rue.
According to their owner, Rebecca Pizzello, Rue sees Bubba as her mum and the pooch is all too happy to take on the role.
On Instagram, the unlikely allies can be seen snuggling under blankets and helping one another with grooming.
Check out some of their oh-so-cute photos below.
