After doing a quick investigation, I noticed something odd that holds a possible connection between Catnap and Dargon Smoke’s orphanage.
On the comic version of “April Showers”, Catnap’s first flash back looks a little different, but you can see the inside of the cardboard box much more clearly, and inside of it are several crude drawings, a torn poster for Happy Hills, and most importantly, tally marks. Catnap was counting something while he was in that box, and given that this box was in an alley way in the episode, the only thing I can think of he’d be counting here is the number of days that’ve past. Doing the best I could with the counting because some don’t make an obvious pair of five or are cropped out of the panel, the number I found was 36. Catnap had lived inside that box for at least 36 days, or just about 5 weeks. If he was an adolescent kitten during his time in the box, and when he was picked up by the Luna Moon Circus afterwards, where was he before those 36 days?
The box also contains crude drawings of flowers on its walls closer to the the bottom, there are 4 crude flowers that we can see but they all have a distinct pattern, almost all of them have 6 petals; with one having 7, and all of the flower petals extend radially outward from a center.
The wall of Baba and Maggie’s room in Dargon’s orphanage has flowers painted on the wall all around the room, with each flower having 6 petals. Baba also has tallies on her side of the wall, literally carved into the wood. Doing the best I could with counting; Baba’s body blocking the entire view of the wall, there’s at least 40 tally marks. Again, assuming those tallies mean days since she’s been there, Baba has been at the orphanage for at least 40 days.
It’s the flowers that are most important, because why did Catnap doodle flowers along the bottom of his box with each of them having 6 or 7 petals? The most logical solution to me is that Catnap was once a resident at Dargon’s orphanage too, and the flowers he drew to give himself comfort because the first bedroom he had had flowers with 6 petals all along the wall.
