It was nearly midnight before the cat moved at all.

[diamondcutter]

Mr. Dursley might have been drifting into an uneasy sleep, but the cat on the wall outside was showing no sign of sleepiness. It was sitting as still as a statue, its eyes fixed unblinkingly on the far corner of Privet Drive. It didn't so much as quiver when a car door slammed on the next street, nor when two owls swooped overhead. In fact, it was nearly midnight before the cat moved at all.

No, it means 'in any way'. The cat didn't do any moving until midnight.
