Case in point:
During a rapid-fire Q&A with inquiring minds on Twitter, an apparent Katy Perry fan (handle @perryproud) asked, "do u love the katycats?"
"Of course. I love all cats. X," Brand cheekily replied, making light of the question about whether he still cares for his ex-wife's feline-inspired super-fans. The moniker was bandied about beforehand but really took off after Perry's Hello Katy Tour.
As for Perry's one, true, literal KatyCat?
No word on whether Brand ever sought visitation rights.
