Some of the interviews, including this one, have the original audio available in the post without any TTS shenanigans. It's illustrated with a Cricket photo in which he's posing vainly in a patch of sun, stretching out one wing.
It establishes the biographical facts of Cricket's life. He began in a dungeon which appeared in York, Toronto. Like most, it was new; this was its first and only appearance. It was four-dimensional and the monsters were assorted larger and meaner and winged versions of various animals. Traceless dug up after-action reports and apparently in addition to the giant winged cat, there were reports of a dog, a gecko, a squirrel, and some kind of frog, but since the dungeon was 4D, a lot of the suspected monsters were never seen in their entirety, they just reached kata or ana and killed people who were trying to hold the entrance from the dungeon end. An esper with a homing power that works across the fourth dimension was hauled in from Manitoba by teleport after the dungeon monsters started escaping and the dungeon's urgency level was escalated accordingly. That esper, Columba, located every identified victim of the dungeon and pulled them out, over the course of a few grueling hours with a lot of guiding breaks, and then homed in on the dungeon core and killed it. Meanwhile, more local teams were trying to deal with the escaped monsters. They killed most of them, but by the time the winged cat - the size of a black bear and venomous - was tracked down, the dungeon was dead, and the cat had shrunk to normal cat size and lost the venom and addressed the SWAT team in English. (He said "what the fuck is your problem".)
There's not a lot of robust policy on benign-ified monsters, but the SWAT team nonlethally arrested the cat and held onto him for a little while before the Maple Esper Agency's in-house research department received custody of him to investigate his properties. There's an X-ray, on the blog, showing how the wings attach, which was taken during this time. Cricket remembers vanishingly little of being a monster with a living dungeon and it's easily possible that every snatch of memory he is able to conjure up is a later confabulation or maybe localized to the few minutes in which the dungeon underwent its death throes. Analysis of his accent and vocabulary gets results like he grew up in York. Eventually MEA offered to get him food he liked more than normal cat food if he would help with a 4D dungeon; he did this, in Rochester NY, proving able to extend into and see across the fourth dimension just fine even in diminished form. However, he still had a very low opinion of everyone at Maple and refused to answer to any name they tried to give him (there's a list, which starts with Fluffy and ends with Cata).
During Traceless's awakening he decided he should get a cat - originally intending to get a completely normal cat - as a failover for backlash compulsive socializing during the inevitable moments when no human picks up the phone. Traceless's mother posted about this on an esper forum frequented by a Maple employee who offered - initially somewhat jokingly - to provide a cat. Traceless, once awakened, went to the office where Cricket lived and offered to teach him to read - he's native-fluent in English but began illiterate. Cricket reports taking an instant liking to this most worthwhile of humans, and went home with him that very day, and accepted the name Cricket, and insists on reporting to him and no one else, even though Traceless can't himself operate in 4D, when dungeon-navigating. Cricket now spends most of his time watching television (it's good for providing conversation topics when his human is backlashed and needs to be purred on and talked to) and gets sashimi four meals a day. He says being in 4D dungeons is nice because his fur can go in all the directions it's supposed to but he doesn't really mind being projected into three dimensions most of the time.
