Thanks again for the well wishes, folks!
MBarnum, my friends are moving and she has developed an allergy to her cat, Walty, so they have been looking for a home for him so she could be in a cat-free environment in their new home. The Gal finally broke me down, and we are going to give it a shot as a two-cat household starting Saturday. I know Walty, and he seems nice. The quesion is whether he will get along with our Killbot, who is also very easy going. You never know!
