Lily and Rose are two sweet girls who are born on the same day and are neighbors who will grow up together. As toddlers talking baby talk to each other, no one understands what they say. A yellow and white cat named Daisy comes up to their playpen because she understands their language. In turn, Lily and Rose understand Daisy who gives them mostly good advice about staying away from poison ivy and keeping away from the street where cars go by. She also tells the girls to stay away from a big brown, furry dog. They pay attention and listen to Daisy because she knows things. One day when the girls are in front of their houses, they wait for Daisy to visit them. Oddly, she has an untouched bowl of milk that is still on the front porch. They speculate about where Daisy might be. Then the big brown dog, Cactus, comes up to where they are and begins barking. Lily and Rose are a little afraid of Cactus, the big dog, especially now that he is looking up and barking so much. They look up in the magnolia tree where Cactus is also looking, and they see Daisy stranded high up in the tree. They realize that is what Cactus was trying to tell them that they didn't understand because while they spoke cat, they didn't speak dog. One of their mothers heard the barking, saw Daisy, and called the firemen who came with their tall ladder and rescued Daisy. When they were all together, they realized that they misjudged Cactus and all became real friends.
