“Harry lost any sense of where they were: Streetlights above him, yells around him, he was clinging to the sidecar for dear life. Hedwig’s cage, the Firebolt, and his rucksack slipped from beneath his knees —“No — HEDWIG!”The broomstick spun to earth, but he just managed to seize the strap of his rucksack and the top of the cage as the motorbike swung the right way up again.

Malfoy fell backward on top of the Death Eater, his mouth bleeding, utterly bemused."And that's the second time we've saved your life tonight, you two-faced bastard!" Ron yelled.”
“MacRieve had been roaring in his cage in the basement for hours now, […] "Let me the bluidy hell out of here!" sounded up from below. Regin glared at Lucia, as if this were her fault. "He is harshing my buzz, and I am" – Regin turned to yell over her shoulder – "not interested!" "Open this fucking cage, you glowing bluidy freak!" Gods, he was fierce.”
“...and his bones were a cage of ice.”
“...That insurgent horror was knit to him closer than a wife, closer than an eye lay caged in his flesh, where he heard it mutter and felt it struggle to be born; and at every hour of weakness, and in the confidence of slumber, prevailed against him, and deposed him out of life.”
