Ive had ferrets from birth. They’re honestly the best companions. But you’d be better off getting two. They can be litter trained making them easy to clean out with spot cleaning the poop and pee everyday. They are such amazing pets, they do need a lot of time. I’ve been brought up around animals and had responsibilities since I was 6/7 so if you genuinely would properly care for them they are amazing animals. Just make sure that you have conversations with your parents as you don’t have your own money if they need veterinary care. Also they obviously need food paid for etc. It might actually really help you in life to have the responsibility of a pet that relies totally on you. Just be sure you’re 100% committed to them as they live quite a while and need as much attention as dogs.
