Gaiman said the same thing about Harry Potter.
Gaiman: Well, yes and as I finally, pissed off, pointed out to an English reviewer who tried to start this again, I said: Look, all of the things that they actually have in common are such incredibly obvious, surface things that, had she actually been stealing, they were the things that would be first to be changed. Change hair color from brown to fair, you lose the glasses, you know: that kind of thing.
LR: Change the owl to a gecko.
NG: Yes. Or to a peregrine falcon. And I said to her that I thought we were both just stealing from T.H. White: very straightforward. But then I saw an online interview with the mad muggles lady where they were asking her about me and they said: what about Neil Gaiman? And she said: Well, he's been gotten to.
