Where to find specific adoptable pets?

Unfortunately I was not successful in recovering my childhood account, however, I made a new one ( username: MattRonn, feel free to send a request to play games! ), in memory of my past and current pets. <3

I'm specifically looking for a "Black Cat", and a Tortoise Shell type looking cat to adopt on my account, but I didn't find either of these types of cats on the online Ganz store. Where else can I look for these types of pets? Thank you!
