Hi Pam,
I have carpets throughout except for kitchen and bathrooms and didn't really find the occasional accidents (I had a litter of 8 pups last year so more occasional flood :P ) too difficult to deal with - if you clean up asap it's not a problem and should any seep through the carpet itself, make sure you also wash over the underlay too and your home should remain fragrant.
Afraid I really can't help you on the cat mounting issue - sorry, have a mental picture which is making me laugh till my eyes water :D Poor confused Stuart Little :D I've never known a resident cat yet that couldn't sort out a young whipper snapper PDQ if it really wanted to so as long as they always have an escape route and can either remove themselves to another room or jump high out of reach then I'm sure the attraction will eventually wear off ;)
Give the cute boy a cuddle from me, Teri :)
