I have the same problem with Lion and Bear - two neutered male cats - not that it is actually a problem, just an occasional nuisance. Lion and Bear have always sucked and kneaded on my housecoat, several sweaters, a wool knit shawl, fluffy scatter rugs and things like that. They don't just suck on them where they find them, however, but carry these items through the house, walking with them still in their mouths and dragging the item behind them, stopping every now and then to knead a little on the item, then move on to another location, purring the whole time. I find these items scattered all through the house, regardless of where they start out.
Dirty laundry is especially enticing to them - especially something that my husband and I have worn right next to our bodies. They roll around on the clothing, rub their heads against it, and then often will pick up items like underwear, socks and bras (yep!) in their mouths and carry them out of the laundry hamper or laundry room into another part of the house. This is what becomes embarassing!
They also like to carry their toys around and really like the little spongy foam rubber balls or the plastic coils. They will jump up onto the bed with one of these in their mouths and play with it there when we are asleep. We wake up to find the bed littered with cat toys:-).
When we had an indoor stairwell they spent hours carrying the balls to the top of the stairs, letting them drop down the stairs, chasing them down and capturing them at the bottom, then carrying them back upstairs and dropping them all over again. Actually. they picked this trick up from one of my other cats, Freija, who originally discovered it - and four of them would be involved in chasing and dropping and chasing and dropping - all together. I sure wish we had a stairwell now - it would keep them occupied!
When they were little and teething, anything on the ground ended up in their mouths. I remember one morning when my brother was visiting from out of town for an appointment, he took his watch off and left it beside the bed. It wasn't there in the morning and we frantically searched the house trying to find out where they had taken it in time for him to make his appointment. Finally, the alarm on the watch went off and we found it underneath a dresser:-).
