Hi Siamese Kelly....what do you do with your calling queens? Is it not as hard on them coming into heat every 2 weeks as it is to let them get pregnant? What a nerve wracking little bunce of hussys our cats are! I doubt if herbal stuff is even heard tell of in this neck of the woods. I am considering letting Angel maul her with his stud pants on ....thus hopefully throwing her into a false pregnancy. This happened with one queen before when the male was too young to mate and was practising ..... she had 2 two month long false ptegnancys before he actually bred her. It sure stopped the blasted heats for awhile. How do you manage your male without stud pants? Mine is a sprayer and has to wear them whenever I let him out of the bathroom.
