I just got off the phone with the owner of Body Boutique. She's a reasonable woman and we worked out our problem. We've never had a problem with the actual service that Body Boutique offers, just the way they handle closing an account. While I can't say I agree with their practice, I can say that the owner handled the situation correctly and our problem has been resolved.
They will try to charge you pet rent. I had to take them to court to get back hundreds of dollars they tried to bill me for move out and to get money back for "pet rent." It is not legal in Lawrence to charge additional rent for pets. Don't fall for it.
