I have great news!!! We're going to be able to bring in that grey after all!
Apparently the rats have gotten so bad from feeding off the scattered bird seed around his outside cage that last night one entered their home and scurried across the son's chest while he was sleeping. That is the final straw, so now we can bring him in for some rehabilitation.
Could he have picked up any diseases from the rats? I need to know what we could be dealing with. He'll be quarantined in my son's bedroom while we look for his forever home.
Perhaps there's someone in Southern California looking for a CAG in need???
