Gyps,
I don't KNOW that what I'm saying is true in this case, but I would bet that Prys being sensitive to anesthesia means that while with other breeds one in 500 reacts badly to anesthesia, in Prys, it's like one in 200 or something. Technically your odds are two and half times greater of Sheba having a problem than a non Pry, so that is what people talk about, but really, the high odds are that NOTHING will go wrong.
They do this to older women who want to get pregant. "you're 40, you have 1000 times more chances of having a mentally retarded (or whatever condition is being exagerated) child than someone who is 20"
BTW for any BPO'rs on the board, if you are older and trying to conceive or you are pregnant and some insensitive tardlet says this to you, tell them that you have a 100 million times more chance of providing a stable healthy home than a 20 year old (it isn't statistically accurate but people don't usually care about that anyway)
Sorry about the tangent, this happens when I'm tired.
Gyps, Sheba is adorable and she will be FINE! You will be snuggling her and smooshing her face SOON!
