Mogwli...peeping on mommy's bed is a big no-no.

Lacey....I agree with Debbie, he maybe needs/wants his own litter box. Also try a different litter...Tigger will not go in the clumping litter....only clay litter. I would also check with your vet about urinary crystals.....if he has these he will tend to get the urge to go at various times and if he does not think he will make it to his box, he will go where ever he is...the bed, the towels, the carpet, etc.
