You might also want to look into adopting a Bengal Cat, another spotted breed developed from domestic cats and Asian Leopard Cats. After researching and buying ours, I find many are available on Petfinder. I'll give you the good, bad & ugly about Bengals.
We have two: an F3, Rocko (known as early generation as he's only 3 generations removed from the ALC) and later adopted his great-grandma, Millie, a retired breeder with pedigree as long as my arm. She essentially has the genetic make-up/needs of a big-ole tabby cat with spots.
(Possible interesting side note: Millie is a Millwood cat bred by Jean Sugden Mill, a geneticist generally credited with furthering the Bengal breed. It originally started as a program to breed ALC's with domestics to insert ALC's natural immunity to feline leukemia to domestic cats. Her daughter, Judy Sugden, is developing the "Toyger" line.)
We've had "alley-cats" all our lives, but Bengals are generally more dog-like in their needs: they require companionship, stimulation and regular attention. Don't expect a docile lap-leopard. Get two for your sanity. Even Millie, our grand old dame, needs to poke her nose into
everything you're doing, does the Bengal 500 Race around the house twice a day and lets you know verbally WHEN she wants to be fed, let out to the lanai or whatever. We had to change all our inside door latches to knobs when she discovered how to open them.
OTOH, as Charade mentioned (and I can't totally disagree with his assessment in hybrid breeding), our EG is illegal in some states as the breed is sometimes misunderstood as to their "wildness". ALC's are not aggressive, but intensely shy nocturnal cats found in Asia.
I don't recommend an EG for everyone as we refer to him as our "special needs" cat. His "wildness" extends to a special raw diet - commercial cat foods have "explosive" results.

And extra-extra litterbox cleaning diligence ("my litterbox is not impeccable?? I shall use your empty laundry basket, plastic container or bathtub!")
Sigh. Hard to describe why we put up with it, other than he's the MOST affectionate, sociable, endlessly entertaining animal we've ever owned.
