Q: How many is too many ferrets to a business (group)? I say it can be up to 10, as long as they get along.
A: I have never heard anything definitive on this. Some people can house large numbers of ferrets together while others can’t. It would depend on available space and resources (litter, water, food).
The best idea would be to stick with an average litter size of six or so ferrets. We can’t look at the wild counterparts of ferrets to assess group size because polecats and black-footed ferrets are not found in social groups.
