Good for you, good for Dr. Tom, and good for Buzzy --I hope! It can be difficult to find a vet who doesn't automatically assume that just because a cat is FeLV+ (or FIV+ or has other underlying problems or is aged) can't be helped. Two problems at once doesn't always mean that they are related, and it's worth a shot to treat the problem as if the cat were healthy otherwise.
My other peeve is that many vets, at the mere mention that a cat is indoor/outdoor, assume that the cat has some dire disease (and that the owner is not a caring person with love for his pets). I've been through that many times and gone home with "death sentences", just as you were supposed to do. I always did just as you did. I researched for hours and hours, then found a vet who was willing to think and listen. None of the "sentences" were imposed!
Before you criticize someone, you should walk a mile in his shoes. That way, when you criticize him, you're a mile away and you have his shoes.
