How do you want it split? The body splitting tool must completely intersect the body. I split it down the middle as an example. Model is attached.

I would probably do this in the Mesh environment. Trying to do this in a BRep will leave big planar areas of your model that won't look right. The basic idea is:
- select and delete mesh facets from the arms
- use either Repair or Erase and Fill to close the holes
- then, convert to BRep
if you share the original mesh, I or someone else can show you how

The video below illustrates a few techniques. It also illustrates how painstaking this process can be (I apologize for the length here...). Better mesh users can probably do this much faster. But, the basic idea is: Select all the facets of the arm, and delete them. Lots of selection tricks here - Expand/Shrink, using window select vs freeform selection, etc. Take your time, delete a bit at a time. Then, the real trick is: if you have an opening in your mesh, select one facet, then go over an adjacent facet and do "shift-double click". This will select the hole boundary. Once that is selected, use Erase and Fill to patch the hole. Play with the density until you get about the density you are after. Repeat for the other arm...

I took off all the arms, legs, and tail. It would be better for you to learn to do it, but, in case you need a reference mesh, here is what I was able to do with the techniques I described in the video.

That was what I said in the post was "the real trick" in this method. It is totally non-discoverable, I admit. What you do is:
- with "Face selection" enabled in the Mesh palette, select just one mesh face/facet:
- move the cursor over an adjacent face and double-click, while holding down Shift:
- this will select a region around an open hole:
Here is a shorter video. It doesn't really capture the Shift-double-click, but that is the trick:
