You might want to stress that where you can take the kittens back or have them returned to you this will be with no monetary compensation to the other party. Sad as it may seem someone could ask you for payment of their expenses or to compensate them for money spent on the cat / loss of their cat. I'll take a look at the breeder's contract I have for Mouse when I get in from work and see if there is anything else in there. I think there might even be an article about it on site and will take a look for that as well.
