Pam,

Little Bella is adorable!!
I too have gone the introducing puppies to cats route a number of times, and the cats DO come around eventually, don't worry about that! My adult Labs (10 and 4 y.o.) still sleep in their crates in my bedroom, and that won't change. They get an extra 8 hours or so of your scent, and even though they're sleeping, it seems to register with them that you're there.
Good luck with Bella!

Happy
