The Basenji Klub Deutschland has a website - otherwise, email me privately for some addresses. You could be too late for this season's crop though you can get on a list for next winter.
When you breed your bitch, you are putting her life at risk. Sure, problems don't usually happen but they occasionally do; would you know how to recognise them, and would you know what to do? I have had two emergency C-sections done and they can be quite expensive. Breeding is not cheap if you do it right, so if you think you're going to make money...

As most basenjis are born in Dec, you are very unlikely to find a 2 month old at this time of yr, but you could get on waiting lists for this years breedings.
My gut feeling is if you can't find a dog who is utterly good with cats already, your best and safest bet is a puppy. I suggest you get on a couple of breeder's list and wait for the perfect pup for your house.
