Arthur -- Lurking danger, or fuzzy hor d'oeuvre?

No: HPFGUIDX 139659

Rereading HBP, I noticed the following in the account of the party
after the quidditch match:

[Harry] walked straight into Ginny, Arnold the Pygmy Puff riding on
her shoulder and Crookshanks mewing hopefully at her heels.
...
[Ginny] walked off to help herself to more butterbeer. Crookshants
trotted after her, his yellow eyes fixed upon Arnold.

So is this the cat part of Crookshanks viewing Arthur as a furry
little snack, or is the kneazle part keeping a close eye on another
dangerous beastie?

Discuss.
