Part of the common feline aversion to cat carriers is that it is a new and scary place. Cats also rapidly figure out that when their cat carrier is visible it’s time for a journey, and this negative association can make getting your cat into their basket even worse.
Getting your cat basket down a few days early, or having it out all the time if you have space, is a great way to take away some of the fear associated with their cat basket.
By having nice, comfortable bedding in there, or popping some yummy treats inside, you can help your cat start to associate the basket with pleasant experiences. This might not make them enjoy a car journey, but feeling like they are in a familiar place can make the trip less anxiety-inducing.
