There certainly was an expression of surprise and mystification on her face as she saw the change that had come over those kittens. They had shrunk and faded from two or three bright colors to a single pale pink. She looked again and sniffed them. Their odor had changed, too. She turned to the watchers about the table, but they said nothing. She hardly knew what to think. She was half inclined to leave them and go back to the basket, when one of the squirrels whimpered--a genuine, universal baby whimper. That settled it. She was a mother, and whatever else these things in the hat might be, they were babies. That was enough, especially as she needed just this much baby here in the hat to make good what was lacking in the basket. With a soft, caressing purr she stepped gently into the hat, took one of the squirrels by the neck, brought it to the edge of the table, and laid it down for a firmer hold; then sprang lightly to the floor. Over to the basket she walked and dropped it tenderly among her other babies. Then, having brought the remaining one and deposited that with the same mother-care, she got into the basket herself and curled down contentedly--her heart all whole. And this is how strange a thing mother-love is! The performance was scarcely believable. Could she be so love-blind as not to see what they were and not eat them? But when she began to lick the little interlopers and cuddle them down to their dinner as if they were her own genuine kittens, there could be no more doubt or fear. The squirrels do not know to this day that Calico is not their real mother. From the first they took her mother's milk and mother's love as rightfully and thanklessly as the kittens, growing, not like the kittens at all, but into the most normal of squirrels, round and fat and splendid-tailed. Calico clearly recognized some difference between the two kinds of kittens, but _what_ difference always puzzled her. She would clean up a kitten and comb it slick, then turn to one of the squirrels and wash it, but rarely, if ever, completing the work because of some disconcerting un-catlike antic. As the squirrels grew older they also grew friskier, and soon took the washing as the signal for a frolic. As well try to wash a bubble. They were bundles of live springs, twisting out of her paws, dancing over her back, leaping, kicking, tumbling as she had never seen a kitten do in all her richly kittened experience.
