Looks like some more aresenal might be in order.
Either my cat got him and didn't tell me, which would be unusual, or he went to a different restaurant last night...... I only had cheddar cheese on hand as far as suitable mousebait, so will try a little peanut butter tonight and set another trap downstairs on a shelf close to those pipes, but one that my cat can't get up on...... I think.
Give us this day our daily bacon.
