Jen,

Karen's right. The more handling, the quicker they come around. One thing you can do is wrap them up in a towel with just their heads exposed. Pet and kiss their heads, gently blinking your eyes and whispering to them. Sometimes feral cats will hiss and spit when you first approach them. Don't pull your hand back because that will show them you're afraid of them. That is just a defense mechanism. Pick them up and hold them close to you, again, whispering to them and petting them constantly. Eventually you will hear purring. They will be eager to jump back into their cage. Don't worry. Just keep doing that and also, offer them canned food from your finger. This will let them know that you aren't a threat to them. The more food you give them, the more they will let their guard down.

I just got through working with 3 feral kittens about 5 weeks old. Unfortunately one died from dehydration. The other two, Isabella and Tucker are now in foster homes doing great.

You will also notice that the more you talk to them, they will begin to respond to your voice. Once they start purring, that's half the battle.

Good luck, Jen. If you need any help, please let me know.
