Nope, can't say I do know. I've always done it that way. Gotta keep putting them in there. Get them use to using the litter box then get them use to using a covered/dome litter box. You're also gonna wanna get a scratching post for the kitty so it knows that that is specifically for scratches. :) I spray down my cat's scratching post with catnip scented spray so they rub on it and love on it.
Haha. I think you'll like it here once you get use to the layout. :) If you have any questions ask away. Don't forget to make an intro thread. :D The more you post and chat the more money you make. Also, no one word posts, bumping threads or posting 3 times in a row. Give threads a chance to survive before ya try to bump them up. :)
