Thanks guys.

I can't say about breeders, I didn't look at the sites as I wouldn't know what I was looking at anyhow. I will just comment on the breed. Terriers do have a high prey drive. OK so not each individual animal within the breed will have that. But remember, you have cats! Yes it is possible to find a Yorkie who gets along with cats fine, no problem. It is just a bit more . . . challenging to find the right dog.
That's what I read, and they aren't very good with other dogs. But if they are raised with them won't they be ok?

The first breeder has thirty dogs (22 are bitches) and had four litters from June 11-25
I never saw that.

I have seen in the dogs annual magazine a listing for OZyorkshireterriers but I cant finc the site. Every time I type them in it says it doesn't exsist.
