I know that some vets will not anesthetize cats even for domestic flights.
For this reason, I really do NOT want to use anesthesia on my 2 cats that are both 16+ years old.
Especially on a flight that would require enough anesthesia to keep them out for 15 to 18 hours.
Is there an alternative?
Will any airlines let you buy a seat for your pet carrier?
Are there any sea going options?
