My DH and I spend many years trapping, neutering and when possible taming and rehoming feral cats
TBH if these kittens were truly feral, they would not be safe to be around Cod's children. If a child had cornered one, they would be far more dangerous than a domestic moggie.
Sadly I think Cod did the right thing and the shelter did the wrong thing in adopting out feral kittens to a family home.
I don't agree with rehoming cats because you get bored, or they get old/sick...but feral cats are a different issue all together.
