Although I could find some online articles about traveling with cats, their advice was too general to really help me. What I needed was specific information. I wanted advice on which type of carrier worked best for the ride. I would also need to transport the cats to a pet-friendly hotel room on the overnight stays.
It took a lot of searching through various advice pages, and reading Amazon reviews of cat products, to finally decide what I would try. Some items I bought were returned, and some worked out very well.
I'll share my first hand experience here for those of you planning a similar excursion.
All in all, the 3-day trip went better than expected, and the cats settled down and accepted their circumstances after the first few hours. By the second day, they were quiet the whole day.
