Has anyone had this happen? I have an 11 month old male Savannah who bred his yr. old companion. They've been sharing living space for about 5 mos. and were introduced to each other by their breeder before I picked them up knowing that I was going to breed them. He bred her for the first time (and the first breeding for both of them). She did not become pregnant; she's an F1 and he's an F5. A week later my F2 went into heat and although they are great pals and she tried her best to entice him, he would not breed her. Then just last night my 2nd F2 went into heat and he would not breed her. She was terrified of him until she went into heat and then she did her best to entice him as well. No Luck. Any ideas about what might be wrong? They were alone in a room. When he bred the F1 they running around loose with everyone. We're a small cattery of 7 cats so they all know each other well and my male does not spray so far. Thanks, Sue from Northern Savannahs/w/Love
