When I was about 10 I read an American chns'/young adult book in school, but I can't remember the name of it, and the details I do remember are very random.
Main character's name is Lewis/Louis (one of these spellings but I remember the pronunication). The title had the word "like" in it, but I don't remember where it was placed. The main character had a friend with a cat who bites, and I remember that there were two babies who were very minor characters, called Gertrude and Matthew (so presumably this was an older book!) Any ideas?
