Wow folks, thanks for your input.
There really is a lot for me to think over. Honestly, it does sound like hard work, and I'm not yet sure that I have enough space or money to manage it.... So I will not be rushing into it. Thanks too for the info about early generations in breeding, honestly I was quite ignorant to how this may differ and present other challenges.
My breeder has been really helpful to me so far with other Bengal questions I've had and we are in regular contact as I keep her up do date with how my cats are doing. She has told me that there is a lot of hard work in breeding these cats, and I'd be on a steep learning curve. Perhaps I'll try to go and spend a couple of weekends with her sometime and see how she works things, get some experience of the work involved, learn more about it. She's a few hundred miles away, but I think the travelling would be worth the knowledge I'd gain. She is a larger scale breeder, so would be different to me, but I'm sure I'd get some useful insight. I think there is another breeder closer to home, so I may try contacting them too for advice, if they are willing to help.
It is my intention to build the kittens an outdoor enclosure from the back of the house so they can enjoy fresh air and some more space too.
Thanks again folks, for now I'm going to enjoy their kittenhood. Xxx
