State laws for Pet Foxes:
REMEMBER THAT city or local ordinances still prevail over all these laws. If the city or county in which you live prohibits the possession of such an animal where you live, you would be in violation of local ordinances. To find out the laws in each city and county, you would need to check with each entity individually.
UK-England, Scotland, etc:
you do not require a permit or any other paper work as they are not on the DWAL list.
as for paperwork there is none which is a bonus to living in the UK plus you can move anywhere you want in the UK and you can take your furry friend with you.
