The media had been surprised, and had subsequently had a field day over it, but none of the Kaitou KID Task Force, nor anyone else who knew the thief somewhat directly, found it strange or uncharacteristic of the thief when, right in the middle of a heist, he'd abandoned his stage mid-performance in favor of swooping sideways at break-neck velocity in front of a speeding truck to save a cat.
They knew about KID's No-One-Gets-Hurt Policy, but honestly, even if he was confident in his ability to save the feline without being harmed himself, he was still a complete lunatic.
