We have two longish car journeys coming up with our two cats. Five hrs on the first and five-six hrs on the second. They’ve barely been more than 5 mins in the car on the rare trip to the vets. So I’m not sure how they will react or behave. I heard you can get some sprays or something that you can spray the carrier with eyc. Or maybe a medicine or something. Has anyone used anything they’d recommend?
