The bloodwork is just a blood test to show levels in the blood checking for liver functions, blood platelet count etc. I just had Sawyers done yesterday and his nutering will be done tomorrow. it was around 60 dollars, but I would definetly have it done. Especially as your baby is small and young. it insures that she will not have trouble with the anesthic. As she will have two procedures done, I would make sure it is done. It may cost a little more, but it is the one thing you can do for her as you can't do the actual surgery. I have heard so many times of things found in advance of surgery that may have saved a puppies life. That is just my opinion, I am sure your little wildcat will do just fine.
