One day, a big cat and a little dog were sad. They wanted to unite and play together, but other animals said they could not. The big cat and the little dog did not like this. They wanted to show that they could be friends.
The big cat and the little dog found a ball. They played with the ball together. They were very happy. Then, a mean bird saw them play. The mean bird was angry. The bird said, "You cannot play together! I will make you stop!"
The mean bird found poison and put it on the ball. The big cat and the little dog did not know. They played with the ball again. They started to feel sick. The big cat and the little dog were very sad. They could not play together anymore. The mean bird was happy, but the big cat and the little dog were not.
