When it comes to animals, enough is never enough. Learning never stops, even after decades of being involved in breeding and/or owning certain species. The research part of exotic animal ownership won't ever come to an end. I invite you to visit the following websites and resources, join the following groups and ask as many questions as you want! Remember, all foxes are individuals too. No fox is the same - like humans - and antics or reactions can differ, therefore asking others in public groups might come in handy as some may have foxes that react similarly to yours; the insight they can provide could help you understand your fox in a better way.
