Is Phyllis' face looking better?
Also not sure if it will work with Phyllis but when Caesar pushes, if i slide a door open and leave it about halfway open, Caesar will sit with his face hanging out and looking at stuff or resting on the litter dam. Sometimes though it doesnt work the best and Caesar will try and climb on top of the cage stack or look inside Vicky's cage lol. But most of the time, it quiets him down and after a while he will go inside a hide and sleep.
