Mr Sprinkles

From Tardis Wiki, the free Doctor Who reference

"Mr Sprinkles", (PROSE: Rachel Survived) or "Mr. Sprinkles", (PROSE: White Canvas) was Graelyn Scythes's pet cat, who lived with her by 2471 in Moscow in her native universe within the 10,000 Dawns. He appeared as "a grey kitty, wearing a white collar with a rainbow sprinkles pattern on it", justifying his name.

Seemingly having an augmented lifespan relative to 21st century cats, he was still with an adult Graelyn during her interdimensional adventures as an agent of Dawn, following her to the Totality; he was the first interdimensional visitor that Graelyn Scythes encountered, before she was ambushed by the Arbiter of Knives and then saved from her by Graelyn and Archimedes Von Ahnerabe. (PROSE: Rachel Survived)

After spending fifteen years growing up over again in Auteur's Town with her memories suppressed, Graelyn Scythes abruptly remembered having "a cat named Mr. Sprinkles" among other resurfacing remembrances when she called out to the fictionalised Archimedes Von Ahnerabe through a movie screen.
