Thank you for sharing your experiences!
Love4himies, I thought that with enough time cats would at least tolerate each other's presence but I can see Puddles and Sweet Pea really dislikes each other
It must take a lot of work and patience to keep them separated... I admire you!
BenMax, gosh, you have a great track record! On average, how long does it take before you can leave the new cat and resident cat(s) together without supervision? On some websites they say a week and I've also read it could take a month or more.
Anyway, I will keep you posted on how it goes if my sister adopts cat#2
