Your 3 little porch kittens are just adorable!
I absolutely LOVE the little Siamese kitty!
I actually had a dream about finding 3 kittens in my attic back in 2007 that looked just like your 3, a Siamese, a Tuxedo and an orange kitten. That was before I had my two Siamese and I still had my RB kitty Samantha.
Since you have a Siamese in the litter you should contact Siamese Rescue, they should be able to help you find homes for all of them, they will take in non-meezers too since they are littermates.
They even have a foster home for Siamese in Kansas that you should contact, they can arrange transport to pick them up.
Here is a link, you can try to use the contact link at the top of the page or ask about the kitten named Wendy that is fostered in Kansas.
