When I wrote my checks to adopt him at the animal shelter, I did tell the woman there that I have three cats, and I wasn't sure how this would work out, but the cats are fine, and the little fella (puppy) is respectful toward them. It's going to be a beautiful relationship for all of them!
I will formally "adopt" and keep him...he's so smart, and his name is "Fozzie Bear!"
Thanks all of you!
Patty
