Dusty the Wanna-be Cat [EPUB ebook] 

Dusty is a spunky cat imitating the behavior of others he sees from his window. At first he wants to be an attack cat, attacking animals and people who come into his garden. He discovers that no one likes him when his behavior is unacceptable. Dusty learns that good deeds get rewarded and he becomes likeable. Lastly, when he sees a dog on a fire-engine truck, he wants to be a fire-engine CAT. Dusty is an excellent model for young children. He learns no one likes unacceptable behavior and he becomes likeable when he does good things. Also, wanting to be something other than yourself can be non-ending.
