This is Mog's head. The illustration appears on the cover of the book and again on another page in which Mog has an existential crisis.
She was very sad.The garden was dark.The house was dark, too.Mog sat in the darkand thought dark thoughts.
This is a scene in which Mog dreams of flying.
She could fly everywhere.She could fly faster than the birds,even quite big birds...Suddenly she woke up.
I have the copy of Mog which I grew up with. The binding is only partially intact and it smells like the mold in my parents' basement. Buy a reprint of Mog the Forgetful Cat by Judith Kerr here. Note that the classic phase "Drat the Cat" was apparently an attempt to convert the book from British English to American English. The way Judith Kerr originally wrote it was "Bother that Cat." I should warn you that the reprints use the original text. I don't know why the publishers would think that "Drat that Cat" sounds especially American, but it does have a nice rhythm.
