A kitty in the UK was hit by a car and brought to an animal shelter, but released to the area she was found shortly after, since vets realized she had just had a litter of kittens. Right after she was released, she started howling and the person who brought her back followed her to her litter of kittens, who were severely dehydrated. Thanks to the cat's quick thinking and the attentiveness of the RSPCA inspector, her kittens were saved and the whole family made a speedy recovery.
