I hear they can give the cat a tranquilizer for the trip. Most cats do not like to travel. Even a trip to the vet is an adventure. Cries all the way. Mine do better if they can hide in the dark somewhere. that carrier is prob perfect for when the car is moving. Cats are usually very adaptive. If she is used to using the litter box, she will use it most anywhere. It's getting a cat to pee on demand. Not sure that is even possible, but I have seen my cats hold it for a very long time. Good luck. You ARE a good mom!!!
