Yeah her small size fools a lot of people. I still insist we didn't do enough homework before we got Tallulah and my mom was bent on getting a "teacup." I've actively spoken out against this a number of times on various blogs etc. since she came to be with us.
I'm really fortunate to have a very healthy girl for how small she is, and for that reason, I keep telling myself she's going to do fine. She's such a little firecracker and she'll probably bounce right back from the surgery, but you know how it is being a furmom.
