let text = `Adam was playing outside when he heard a tiny meow! He looked around. Meow! There it was again! He tiptoed toward the bushes. Pushing the leaves aside, he gasped. A fluffy, orange kitten with big, curious eyes stared up at him. "Oh no! Where is your home?" Adam asked. The kitten just blinked and let out a tiny mew! |
|
|
|
|
|
"Mama! I found a lost kitten!" Adam called as he carried the little furball inside. The kitten sniffed around, then jumped up—boing!—right onto the couch. "Oh!" Mama laughed. "Let's give it some milk while we find its owner." The kitten licked the milk happily and purred, prrrr! Adam giggled. "I think he likes it here!" |
|
|
|
|
|
That evening, there was a knock at the door. A little girl stood there, eyes wide. "Have you seen my kitten, Biscuit?" she asked. Adam smiled and pointed. The kitten ran to her, mew mew mew! The girl hugged Biscuit tightly. "Thank you!" she said. As she left, Adam waved. "Goodbye, Biscuit!" he whispered. And in the quiet, he could still hear a happy prrrr!`; |
