I've looked into pet transport companies, car rentals and bringing the cat carriers onto a flight as extra carry on luggage.
All of those options will cost well over 1000 USD, the flight option being the quickest but probably the most stressful for both me and the cats. The cheapest option is one-way car rental but that's nearly a week of driving plus gas + hotel costs means it's still over 1000 USD.
I'm wondering if anyone here knows of an option I might have missed?
It's from near Binghamton, New York to San Francisco, CA
