PATIENCE  PATIENCE  PATIENCE   PATIENCE

Think about this  you are a young child  that was ripped from their home
and shoved into a new situation    would you not be nervous.   5 months is
fine    I have  seen old feral changed before  just  give it time   love and
patience  is the words to live by

For the next couple days  keep the door shut  let them get used to the
surroundings  make sure you keep visiting them and loving them     Later on
let them explore  when they are calmed down a bit

Thank you for taking the little ones  in   make sure  if you have any
question   don't  hesitate to  ask

But please make sure vaccinations, neutering  and FIV test are done

NO YOU DID NOT MAKE A MISTAKE.

Just give them time and do not rush them !!!!  As the other poster
said just let them come around in their own time and they will.  They
have each other to keep company and play with and eventually they will
come to see you as a friend and start coming to you.

After they learn where their food and litter box is I would just leave
the door open and let them venture out on their own into the rest of
the house.  They may wait until night when all is queit and dark to
explore at first and when they see nothing will hurt them they will
get braver.

My oldest hid under the sofa for the first week I had her and only
came out at night even though she knew me from when I took her in as
pregnant and was around her at my daughters before bringing her here.
Then one night I was sleeping on sofa and awoke to find her looking in
my face.

If they really were feral kittens - who had never had positive human
contact - there is no way you would have pulled them out from under the
tub with significant damage.

As others have responded ... give them time.  Since they do have each
other, they may take a little longer to warm up to you than a single cat
would.  But, imo, that's way outweighed by the fact that they will provide
companionship for each other when you're away/busy.

They'll be fine. Right now they have each other so are clinging
together for comfort. At least they're not hostile to you. One of my
adopted kittens (I rescued him off a tree he was stuck in) was so wild
that he hid under the bed for a week and hissed at me if I got close.
Couldn't pick him up without protecting my hands. But he grew to trust
me and became a lovely pet. Not the very cuddly sort, but independent,
affectionate and very intelligent.
