Haha, tigerlily, I saw a quote much like the one you posted, except it said "Get a dog. It's your only chance to choose a family member."
Good luck with your SIL, Tx. I wish my sister and brother in law even liked pets. They'd turn their heads at just my cats...they haven't even met Bella yet, but I'm sure it'd be enough to have them go to a hotel instead of staying at my house. That's fine with me, more room for me and Bella, I say!
I just think how sad it is that their child is going to grow up petless.
