Where could I buy a very small cat in the UK?

I am searching for a very small kitten to buy. I am most interested in the ‘micro’ Persian variety. Although there is a lot of selection in the US, I am quite limited to buying one in the UK for the time being.

I have not had much luck in finding such kittens for sale in the UK. If anyone has some suggestions or recommendations I would love to hear it.

Although I know adopting an animal would be ideal – it is simply not what I am able to do right now, and I require something extremely small and manageable. I respect adopting very much, but it is not an option I am considering currently.

I will want to buy my cat from a small, personal or family breeder – nothing of a commercial sort.

Again, any knowledge anyone could provide me with finding this particular variety of cat in the UK would be greatly appreciated!
