Val saw her little brother, Teddy, in the street. "Val, guess what I've got!" he said. Two small eyes looked at Val from a furry face."What is it. ". she
asked. "It's a ferret! He is cute. My friend Eric gave him to me. He's really friendly. Eric says ferrets are the best pets in the world". "He is cute, "Val said. The ferret had a long neck, and its fur was brown face, like a small raccoon. Val loved it." Can I take it"? Val asked."Sure. But he's my pet, Val, and don't forget about it! "
Val took the animal." He's great, Teddy", she said."You said Eric gave him to you? Why? "Because his mum didn't like it. She says it looks like a furry snake with legs." The ferret looked like a mink, long with small paws and a small head. "Does ded know about him?" Val asked. "Eric gave him to me today, so I didn't have time to ask dad. But he is a super ferret, I'm sure dad will say it's okay. Where is dad?" "He went to the Staples farm, "said Mrs Racer." What's that? That's a weasel! "
" It's not a weasel, Mrs Racet.It's a ferret ", Teddy said." "He's my new pet. "
It's a weasel,"Mrs Racer said," and weasels are bad animals! They eat hens! "
" It's not a weasel, "Val said." Ferrets are different. They don't do all the bad things weasels do. Teddy's friend Eric gave it to him. He's soft and furry like a cat. "
