Just sneaking in & Catching up - poor Shadow! Sorry the vet didn't feel comfortable yanking out those 2 suspect teeth - Tigger only has 4 left, too, so I understand your situation & concern there, completely! But - I imagine if the vet was truly concerned they were an imminent problem, they would have come out.
But - that's good up-front news about the cyst likelihood - will keep you in prayers that it all remains as it is - a beautiful lion-tailed kitty that will shortly be as good as new!
