Buster the dog is 13 years old and cannot move around much any more. Kitty the cat is always there for him, keeping him company every night.

Sometimes Buster would whine all night, but Kitty always comes to the rescue. "Its amazing... She usually sleeps with my sister but Buster would whine all night, so she started sleeping with him," said their human on reddit. Kitty is like Buster's little guardian angel, watching over him and comforting him. Maybe Kitty can sense that sometimes Buster is in discomfort so she purrs to help calm him down.
