So sorry you are going through this Debbie with Morgan & Einstein
I can totally empathize with you
As Morgan has only been castrated 3 wks ago, no doubt his body will still be 'out of sorts' for a while before he settles down.
It may well be, given a couple of months his behaviour will calm down.
What i'm trying to say is don't give up hope yet.
I will send you a PM with a positive outcome we have personally experienced.
