Gerald is probably yowling more because he knows he is much better and wants to go back outside.
There is still a gap inside the wound because when I pump in the liquid to flush it, the liquid goes it and then spouts out like a mini fountain. But as long as there is no pus and no more bacteria, it should be fine when it closes up (hopefully tomorrow?).
“I want to go out, I want to go out!! You have no reason to confine me anymore!!”
