Why is he doing this all of a sudden??
Very probably because he smells the cats ... I would spray the mattress with a mix of alcohol (1/4 cup) vinegar (1/4 cup) and water (1 cup) , mix in spray bottle.
Only correct him if you see him do it , just tell him a firm NO and take him outside. To correct after the fact is useless. And please , never ever rub his nose in it !
