Did you end up taking these little guys in? Do you have any idea how old they are?
I saw an ad on Craigslist yesterday where a lady found two kittens by the dumpster at her apartment complex and she needed help... So I of course drove over there and picked them up

I have taken in kittens before and know it's demanding while they are little, but they slowly get more independent and can eat on their own.
These little guys are about 3 weeks old and I am bottle feeding them every 3-4 hours. I will find them forever homes when they get old enough.
