SHE IS SO FREAKING CUTE! <3
Sooooo happy to hear about how youre going to have her spayed, good fur you!!
Wait, youre supposed to have only declawed cats?

I cant stand when places do that, supporting the cruel procedure of ripping out a cat's claws, bones and tendons. freaking ridiculous.
Good luck with her!
Id say she probably doesnt have an owner, and if she did theyre obviously irresponsible letting a) their cat outside in the danger of who knows what
and b) not spayed.
and if she does have an owner, they should claim her. Try posting on craigslist.org. I wouldnt put a photo, just say you found a kitten and ask that someone contact u with a description.
If I were you, id tell my neighbor that letting an UNALTERED cat lose is the wrong thing to do, she could be hit by a car or hurt by another cat/other animal, not to mention if she doesnt have an owner she will add to the overpopulation of cats, not to mention be exposed to feline AIDS or other cat STDs.
IMO if you want a cat to be able to go outside then you should get a harness and leash, just like dogs.
