A cat followed a kitty through a pet door into a house, so her kittens wouldn't have to live outdoors.

A family was stunned to discover a heavily pregnant stray cat in their house. As it turned out, the cat had followed the resident kitty and snuck into their home through the doggy door.

The tortoiseshell was very friendly, rubbing against her finders the whole time. "They knew she needed help from a rescue because she was very pregnant," Mary Huckabee, Coastal Bend Cat Rescue Officer, shared with Love Meow.

The cat looked as if she was about to give birth, so the rescue immediately arranged for a foster home for the sweet tortie.
