I think you are printing in PLA, which is possible. But I always print this in resin.
I would try to print it at a very low layer height and use a lot of infill to make the parts stronger. And indeed add lots of support.
What you also can do is cut the arms and tail of the model, and print them separately, and then glue them back on.
If that does not help please contact me at massassi.order@gmail.com
