Just deny all knowledge of it .Your word against the cat. Remind it who pays the bills.
Blindfold the cat the next time.
Kill it before it tells your wife!
lol start repenting! Oh...and just FYI...it wasn't just your cat that watched you do it....
just remember.. its his litterbox man..
Its ok.....he's just gonna laugh his a$$ off anyway.....stupid humans...tricks are for cats..!!!!!!!
Give it a treat - that will shut it up.
But then, animals are funny. 'guess that a long, long, time ago a dog of ours (a happy dog, not a "dawg") was under the bed while my wife and I were enjoying a romp, and as she was moaning from my attention the pup under the bed began moaning in sync. We both collapsed laughing and had to regain our composure.
Take pictures of him in the litter box, or licking him-self and threaten to put them on-line if he doesn't forget what he saw. What were you doing, anyway? lol
