Some ferals need much more time than others.

Also you said she put them in a dog crate. Does it still smell like dogs?? If so, THAT could be upsetting the kitties. That crate needs to be cleaned out with a bleach water solution.

Ferals are very unique. Some adapt more readily than others, and then there are some that may never adapt. But I would give these 2 a bit more time before you do anything. And I mean this could take up to 2 weeks, too!

Your friend sounds like she has the patience, help her out by understanding that its not going to be easy the first week or so.

Good luck and keep us updated on this.
