I am sad.Kittens are missing.

Im very sorry!! I know how it feels to have a pet get away. Theres not alot you can do.... 1) look for them all over the area where you last saw them. 2) notify your neighbors that they are missing,that way if they see them,they can inform you. 3) Notify your local animal shelter,so if the kittens end up there,they will inform you they found them. 4) You can also (if you have photos or a good detailed description of what they look like) Put up some flyers around your area letting people know they are missing. Best of Luck to you, dont give up, keep looking for them.
