It was possible to communicate with magic pets through the mind.
However, mental communication would consume mental power, so talking was more convenient if a man and a pet were to communicate over a short distance.
"White Amber?" Roland was surprised. "Why have you changed color?"
"I'm not sure." White Amber climbed along Roland's sleeves and almost reached Roland's shoulder in the blink of an eye. "My new fur is blue now that my old fur is gone. My knowledge is mostly inherited from you. I certainly don't know what you aren't aware of."
Essentially speaking, a magic pet was partially a clone of a spellcaster. Because of the spellcaster's soul piece that was melded to the pet, the pet's knowledge and personality were similar to the spellcaster's.
