This has been a rather consistent weakness of Kira's in this show. He couldn't help but gloat over Shigechi, which allowed Shigechi to escape briefly. He couldn't help but gloat over Koichi, which allowed Koichi to find his identify and Jotaro to recover. And he couldn't help but gloat over Jotaro, which allowed Jotaro to trick him into Star Platinum's range. The dude can't help but give the villainous monologues.
Which I'm sure went fine for him when he lived alone and wasn't fighting other stand users. Now it's just a terrible habit.
I imagine Stray Cat is actually a stand that turns you into a plant and the air control is just a byproduct of photosynthesis (in Jojo logic). Kinda like how Highway Star is a trapping and tracking stand that gave its user super smell as a side effect or how Hermit Purple's spirit photography vines can be repurposed to swing and grab stuff.
