Now don't get me wrong here, I have no problem with my cattails going away...but what could be digging them up? I've noticed several "clumps" of cattails laying horizontally on top of the water, roots and all. While this seemed great at the time, I'd like to maintain some proper "balance" by leaving a few of them in there. In addition, I want to make sure I don't have a nuisance animal of some sort in my pond that could create even more problems.
Thoughts?
