Kitten Help!

my friend was at her Aunts house 2 days ago, and she was looking in the fields because she usually finds something in the fields, well 2 days ago she found a kitten. It is a male FOR SURE, we think he is only 1-2 weeks old because he is VERY tiny. His eyes and ears are open. He has Cat Formula as well.

He pee's and sleeps and walks around a little, but he WON'T poop!

My friend has rubbed his bum and belly, she put his bum under water and rubbed his belly, but he will not poop!:o

Any ideas?

P.S. she called a vet and asked for some info and they told her what to do and she did it, but he won't go.....

Maybe he hasn't had to go yet? I think I would take the kitten into the vet for an exam...AND, double check the fields...there is probably more kittens!!!

I'm no expert on kitties, but I would err on the side of caution and GET THAT KITTY TO A VET!!!
