I'm going to be moving 14 hours away from my home in a few months. I have never traveled this long of a distance with a cat and want to know what I need to do to make her comfortable. Like I said this is probably going to be a 14 hr trip so my main concern is what about her using the litter box? At home she usually uses the litter box every couple of hours. So do I need a large crate that can fit her litter box in it? The next concern is that she hates riding in a car. The longest trip we have taken was 1 hr and she didn't stop freaking out. I have to keep her calm so she doesn't aggrivate her medical issues. Is there something I can give her or do to help her stay calm? Maybe something to keep her cool. She is a persian and just going to the vet she pants(I don't know if that might be stress). Let me know what I need for a trip like this.
