Keep working at it Connie!  I predict you'll have BriBri's and her sister reunited by Memorial Day ;-)

What's one more kitty?  It's not like the kitties are going to fight over who gets to drive the car or blame each other for leaving the refrigerator door open. You'll wear him down; from what you've said he couldn't stand letting a kitty suffer or be put down anymore than you could.  And he does kind of owe you since you said 'no' to the dog and he got one anyway...
