yeah my first
was the price they are trying to get from these cross bred kittens.
Looked like dodgy breeder from that alone.
lollo2304 really looked into this for you, I hope you take her advice
You have heard what she has found about these people selling under age kittens and from random unregistered (not health checked) parents.... please dont support and reward (with cash) a possibly cruel and money motivated back yard business. You will be helping these people continue their questionable breeding for cash.
This add is in West Mids.... and so am I. I would be happy to suggest and recommend breeders in our area if you are looking for a pure bred bengal.
But you should prolly expect any breed of kitten to be far from laid back for its first year or two.
It sounds to me that a young adult rescue would suit you better... adult cat's personality's are easier to access to see if they suit you and they are passed the crazy kitten stage too.
