Just curious - do you breed; if you don't is there any reason why you haven't had them spayed? Is your girl microchipped? If she has been on call then she may come back looking smug. If she does and then has kittens it may be worth having her blood tested afterwards to ensure she hasn't picked anything nasty up from wandering toms.

I sincerely hope she returns.
