I think the issue with injectable anesthetics such as ketamine is that dosage is determined by weight which assumes a certain proportion of fat, which absorbs the anesthetic so they basically calculate to give excess to allow for that. With a lean breed like the Savannah, this can lead to an "overdose"... hence the increased hallucinations but possibly increased chance of death.
On the flipside, I do believe that you should use the anesthetic your vet is accustomed to using. You don't want them experimenting with a new anesthetic protocol on your cat! So if it is a vet that is heavily experienced with ketamine, it might be safer to go with that. But if it is not a vet you know and would trust with your life, you could look at other options in your area?
