" She would've sworn the cat- or kitten, for it sounded quite small- was right in front of her, but there was nothing there.
She straightened and glanced at Val.
His azure eyes were alight with amusement. "Phantom cats and ghostly kittens."
She frowned at him. "I don't believe in ghosts."
"Boring." He kissed her on the nose and, while she was still blinking in surprise, leaned down and did something to the back of the cupboard.
Suddenly one of the boards came away in his hands.
She leaned down again to look.
Staring back at them was a ginger cat, her green eyes wide, and at her teats were a row of wriggling kittens in a rainbow of colors. She was curled in the small space of what was evidently a false back to the cupboard.
"But how did she get in?" Bridget breathed, enchanted. The kittens were at that wee fluffy stage and absolutely adorable.
"Magic," Val said promptly, and then, more prosaically, "or the back of the cupboard's rotted away. "
