I'm quite clueless but from what I (think) I know it's probably too early to choose based on looks. The parents are probably a better indicator of quality and also someone will probably come along and suggest a list of Qs you should ask the current owner.

What about HCM and PK-def status of the parents/kittens? I would think this would be important when choosing stock.

They both seem to have different rosette patterns, the mother is gorgeous though!

Can you not get bother and see over time how they develop, you won't know their real personality until they hit around a year old. I would say the first kitten but then you really can't see the 2nd too well.

You would have to let them grow abit, before considering which queen to pick.

You can't choose breeding females on looks alone, what about pedigree, health?
What sort of breeding of cats have you been doing?
What are your goals for Bengals?

same as above, for me they are too young to choose breeder, you need to look at profiles, ear size, pattern aswell as health & lines and see what your goals will be.

For example I kept a girl back, she ended up with ears that I feel are too big, although her pattern is nice and eye colour and nice profile (could be better though) so have put her to a boy to compliment her and hopefully make her kittens even better than them.

To be honest though I wouldnt start breeding bengals now, I am down to 1 homebred girl, there are SO many bengals from BYB out there I can no longer compete, someone near me studs out his bengal to every single breed going (even states this on his adverts) and he will only sell entire litters on active, even if they are some of the worse examples of bengals I have ever seen, so everyone who buys from him does the same....who do the same... market is over flowing as its more about ££ and charging loads, this sadly is my last bengal litter, just cant compete and lose money at such a big rate that I am

So I wouldnt go into breeding bengals now Id wait get your goals in your mind study the breed own a neuter or 2 show them make friends with breeders etc then get one
