Is Cheshire Cat like us humans?

The Cheshire Cat is niether good nor evil. There are no 'good guys' and 'bad guys' in Alice's Adventures in Wonderland - there are just 'guys'

One of the interesting things about the Alice books is that, even though it takes place is a fantasy world populated by extraordinary creatures, the 'poeple' Alice meets are far more like real people than those seen in the majority of fiction, in that they are not bad or good, they are just people (just like in real life.)
