I had a box of Kleenex in the boat and was just about to take it out. Then I thought, "Hey, if a mouse gets in the boat, he can chew the kleenex all he wants and most likely won't even touch the seats.
So that's my tip, throw in a roll of toilet paper or box of kleenex (full) so the mice have something else to make a nest of, instead of nice seat filling. I also spray my seats with vinyl protectant to give them a bad taste in case they want a little nibble.
If I win the tip of the month again I will auction it off in the lounge and the money will go towards the emergency fund in whoevers name wins the bid.
