Thank You both very much for the advice. When i first got her, her blood sugar was very low because she wouldn't eat. I took her to the vet I go to now and he had to draw blood from her neck to check her sugar. So, I'm confident that he would do a good job considering he took very good care of her since I've had her. You just always think the worst when something like this needs to be done. Thank you again.
I actually have an appt for Feb 25, so if I decide to go through with it, I will let you know how she does.
