5 Hats out of 5 for the Cat
I love reading The Cat in the Hat to my 2 yr old. We have lots of fun reading through it. The first time through he thought it was too long, but now he asks for each each night before bed. I had previously thought he was zoning out during sections of the book, but a few days ago he was playing off by himself and talking to himself and I realized he was reciting part of the text from one of those sections!
Others have expressed concern about the cat and the "things" as role models. You can't explain proper versus improper behavior without examples of the latter to counter with the former. The kids are mostly bystanders, who don't try to stop the cat or the things until pressed at the end. In the end, they take the right action. And, the cat himself, redeems himself to some degree by righting what he has done wrong. The story ends with a question -- that I believe -- is there for you to address when the story is presented and complete: When the mother comes home, should the kids tell her what happened while she was gone?
