Sam is determined to have a pet rat and buys one before he has persuaded his parents that it would be a good idea. In his quest to get them to agree Sam uses everything he can. In a round about way he suddenly lets his parents know that he can read and really doesn’t need the additional support the school is giving him, he shows concern about his father’s health and interest in his father’s model train hobby. He complements his mother on her shoes and then get a killer question in about whether or not his father has seen them.
Finally his parents relent and Sam has his pet RAT. Things do not go as smoothly as Sam hopes and before the last page has been turned he goes from having one pet rat to having nine. Mum and babies are doing well. This leaves Sam more time to widen his interest in pets. Snakes!
