Dog Man slight canon-change idea:
Lil Petey emerges from the cloning machine truly a newborn.
Petey: (*opens machine door, excited*)
Lil Petey: (*literally a newborn kitten; eyes closed, ears folded, looking like a jelly bean*)
Petey, finishes reading instructions: "What a rip-off! I could've done this myself with a test tube and a prayer!"
The mayor and the police get nervous after hearing nothing from Petey in a few days, so they send Dog Man/Greg to sniff him out. Only for Greg to find Petey's lair looking... exactly how you expect it to look for a single parent with an unexpected newborn baby;
Petey, sleep-deprived: "OH THANK CEILING CAT. Here, take him!"
Greg, confused: "Arrooo?"
Petey, shoving Lil Petey into his arms: "TAKE. HIM. I have to feed him every two hours!! AND HE CANT EVEN POOP ON HIS OWN!" (*collapses onto the nearest surface into deep sleep*)
Greg: (*looks down at kitten*)
Lil Petey: (*eyes barely open, squirmy, and mewing!*)
Greg: (*instant love. whole body wagging with parental joy*)
Dog Man manages to argue for Petey to get house arrest for the time being; since clearly cat jail can't hold him, and he has a puppy kitten at home to care for. (Plus the Chief is convinced Petey is in a special form of hell already).
And ofc since the lab isn't baby-proofed, it only makes sense for Petey and Lil Petey to be moved somewhere more appropriate for the time being. And if that happens to be Dog Man's civilian home, then that's their own business.
Bonus thought: Petey didn't disinfect or anything before he made Lil Petey. Who's to say that whisker he plucked had DNA left behind from when it's owner was slobbered on by an affectionate supa cop? Making Lil Petey half dog? :3
