Secret Weapon

Yes I think Blk Jac is a secret weapon 
if the other cats are in my place
he can just by coming into the room
make the others leave,
I have seen Ralph and Gwennie spit at Blk Jac most fiercely !!!!
Blk Jac just carries on regardless
and does not even blink !!
And Etty and Stanley are just scaredy cats
