=== description ===
The man was swimming along the river when he saw a cat floating towards him. He came nearer to the animal to save him from the deep river. An unusual cat immediately accepted help and climbed into the boat. When the man brought him home, he realized it wasn't a normal cat. He had brushes on his ears, and he was much bigger than a regular kitten. Turns out it was a rat kid. The man wasn't afraid of the wild beast because he was still a kitten victim. He was left to be shown and cared for. The kid wasn't against people's caress, and he got used to their caress. He was very loyal and gentle, he loved to chase his savior everywhere. And I saw him as a real parent. A man loved his new friend with all his heart. He left it next to him and tame it. It was a wild rat, but thanks to the upbringing and kindness of the savior. He really turned into a pet kitten. Now he's gonna keep living with his master. And finally, he'll be happy with the new family.
