Holy crap, naughty naughty otter! There otter be a law.

Having an interstate between the river and our casa I don't have to worry about ottervasions, but the bloody raccoons visit our ponds. The large one is too deep for easy access but the smaller one they can just wade in and wreck havoc. I only keep mosquito fish in that one and enough survive the incursions, but I've also learned that water lily roots are raccoon food and I no longer try raising those.
