Welcome Carol! I'm sure you'll love it here and become a cherished member just like your sister.
I'm Kim and have 5 kitties plus 2 when my sister in law moves in with us. I also have 1 dog, 1 grandson, and 3 young adult children (one is technically no longer a teenager since he'll be 21 this summer ;)) I basically live in a zoo. I'm not sure which are the animals -- the humans or the furry creatures. :p
