Hope you have a wonderful vacation, and we'll all be thinking about our Fister boy during his operation. I agree with MOFF that it will be easier on him if he is feeling good rather than have to fight multiple things all at one time. If your vet and everyone agrees, it must be for the best, and you'll just have to think of those bad times when he had to be flushed out to remind yourself that it's for his good that you're doing this. I'm sure he'll be fine, but we'll all be waiting with baited breath until you get back and give us news on how he's doing.

Enjoy Spain!
