OK - I went into more detail in my previous post but I'll just do a quick summary, Kirby still hasn't had his op yet as the insurance company took months to reply and now say they won't help us pay for operation (which our vet says might be quite costly as his bits are growing inside him) and now Lily's gone into heat, and I've caught them countless times mating! no!!!!! We really have not planned for kittens and Lily is till under a year - and even worse, Kirby and Lily are half brother/sister! Now I really need to know, what are the chances of her being pregnant? She's been out of heat for the past couple of days and now I'm wondering, is there a large chance she'd be pregnant? Help!
