What animal is most like a cross between a Pony and a Rat?

Question

Animism studies.

Answer 1

Perhaps your question is a little vague.  You used the word "damning", don't you mean damming.  

If you worship animal deities then perhaps the answer is the one of the many Hindu animal ones.

Answer 2

I'm not sure!     I would not want to catch this sucker in my (rat trap)!
