You should, they are adorable. Easy to take care of as well.
This is sort of true..
It depends on what you mean though.. They can be litter trained so you don't have to change the bedding in the cage every few days to a week..
But they're like *** toddlers that can fit in anything, and they are extremely inquisitive. They get into EVERYTHING.. I'm still 'ferret proofing' my room, everyday they find a new place to go worm into and you have to find a way to prevent it..
If you can shove a beer bottle into it, they will get into it... For a rough size estimate.. Now look around your room/house and look how many places fit that description. They're also really good climbers, they're smart as hell and can like pin their back against something and crawl 'up' using an opposing wall...
