No idea why it worked. It's terrifying.
Tch tch tch
(is there a francophone different one?)
I still do that today, and it works better than pspspspsps. When I was young, if my cat was outside on the porch I could click my tongue and he'd come running from a half block away. What a good kitty he was.
(and for some Australians some of the time, "ps ps fuckin ps, ya cunting cat!" of course. ;- ) )
I mean I don't doubt you, I just thought Brits just say "here kitty kitty" because that's what I usually see in movies and TV shows and so on.
It's funny what you miss when you're not embedded in the culture of a place since birth...
At one point in the book, several of the characters are in South America looking for a jaguar. They ask the synesthetic mage of their group (each character has a different magical background)...
“Got anything to call a jaguar?”
Rider purses his lips. “Well … there is one incantation. But I’m not sure it’ll work. Even the most skilled thaumaturges can’t pull it off more than a quarter of the time.”
Sturgeon shrugs. “May as well try it, Al.”
Rider nods. “Okay. Be quiet, everybody.” He rolls his head on his neck, holds up his arms. Takes several deep breaths. Opens his mouth. Intones, “Here, kitty kitty kitty … here, kitty…”
Chloe throws a clot of mud in his face as Rider dissolves into whoops of laughter. Everybody shakes their heads in disgust and they troop off into the green.
