Beware of rats!

I had previously suggested to my friend that he should close the head intake valve, as some marine toilets will leak past the toilet valve system. He had, almost, but the valve was about a quarter turn open, and the toilet was full almost to the brim. Many toilets are installed so that the rim is normally above the waterline, but, as the vessel was taking on water and not able to discharge it, a disaster was in the making.

The rodent had eaten numerous other plastic items, such as bottle tops. It had also eaten about a third of a tube of toothpaste, and a substantial portion of several stryofoam cups. If it is any consolation to my friend, I believe it is poisonous to rodents! The entry point was the engine hull vent, which had been removed for cleaning.
