Can't We All Just Get Along? (with apologies to Rodney King)

There has to be a reason...I just can't figure it out...
Anyway, in this time of divisiveness and strange incongruities on all fronts, I am learning a lesson from Wilbur and Belle...
We wanted to adopt a kitten to help Wilbur over his grief at losing his best pal kitty...and we were fortunate to have our new little sweet Belle arrive one week ago. She was then 12 weeks old, had been bottle fed from tiny infancy by an angel named Donna, and she is affectionate, curious, playful, funny and hungry!!! 

So...from the second she arrived, Bernie, our terrier, was protective of her...She and Bernie are fast friends...He watches her, protects her, sleeps next to her, lets her bat at his tail and steal his ball.
It is pretty adorable...
And Wilbur? was appalled! Totally not what we had hoped for, but cats have their own language for such negotiations...so we have been doing all of the things people are supposed to do to facilitate safety for Belle and security for Wilbur...but uh...it has been quite the ride.
That primal screeching, growling, complaining, hissing Stravinsky-esque cacophony is a bit...uh, grating, to put it mildly.

I have explained to Wilbur...a futile endeavor to be sure but you know, we have what we have...and my thing is to try to talk it through..but I digress...I have been telling him, "Wilbur this is your kitty!! We brought her home for you!!  
He just looks at me with an incredulous expression...and...

Anyway, it turns out 7 days may be the magic number.
After my getting up at least 5 times to let him out, and then back in... it turns out...finally, Wilbur AND Bernie AND Belle ended up sleeping together...
Omg...
I'm exhausted.

So...this all makes me think about people, and how we do or don't connect...and how we have our own growling, hissing, screeching thing...and you know...
hopefully we can figure it out...
