Cats are heavily reliant on scent and will settle much quicker if their new environment smells familiar.
To help your cat get used to your scent (and the scent of your new home), take an item of clothing or a blanket from your home and leave it with your future pet for a few days before you pick them up.
When you pick them up, place the item in your cat’s carrier. It’ll reduce stress during the journey and help settle them in.
