You seem like a really responsible person, they were extremely lucky that you took on the kittens in the first place, and then that you didn't dump them in rescue when they said they were emigrating permanently. I think they have a real nerve to mess you about this way and obviously don't have the faintest idea of the commitment you need to make to own pets.

I hope the email you have sent is the end of it and they don't give you any more trouble, they really don't have any right to try and claim those kittens back now, especially after allowing you to pay so much for their care.

Lucky kittens to have come to you!
