I have had a cat from across the street having her kitten under my house.
I could never get her or her kittens to come to me or let me get close.
When the kitten got to active at about 6 to 8 week she would take them back across the street.
Even through the kitten were young they still had the wild trait
and wouldn't let me get near them.
If the guys had waited the mommy kitty could have taken them some where else then the men wouldn't have been able to get to them.
By the men getting them now. You know they will get home's and live.
I wish I lived close I would have taken one to help feed. They have to eat every few hours. Good luck
