My suggestion is going to seem harsh, but here it is ..... Without roots or leaves, that "plant" is going to have a terrible time doing anything but "exist" .... You need to cut the stem into sections with 4 or so old leaf nodes and put them in a clear container of water with most of the nodes submerged .... It will take a while, but it will sprout new roots, and eventually push new growth. I had to do this with my Golden Pothos .... Put it in a brightly lit spot but I would keep it out of direct sunlight. Change out the water if it starts looking murky. Within about a month, you should see signs of new growth! =) You can plant the cuttings once the roots are about 1" or so long, or you could wait for the first leaf to open, depends on your comfort level! =)

Is that a picture of the ex ferret?

Just kidding. I have heard ferrets make great pets as they are into everything and provide a lot of entertainment.

If it were my plant and my ferret, I would select some pieces of the ferret... I mean the plant... and do as suggested above, but I might root them in some moist vermiculite instead, only because I find it easier to pot young plants that have been rooted in a cutting mix of some kind rather than water. The roots have 'form' if you know what I mean. They don't come out of the container all stuck together.

Whatever I did not remove from the mother plant I would leave, and let the mother plant continue on to see what she does.

When you put the plant back together again, did you water it in?
