Jo, from watching Emergency vets on Discovery animals, I have seen cats
being in serious danger when eating thread and similar long thin objects
which cannot be dissolved easily or passed through easily like audio tapes
etc. They are particularly dangerous when they get to intestines, where they
can make serious damage. If I was you I'd definitely see a vet  pronto.Maybe
they can make her throw up or something.Although just seen that was 24hrs
ago, so the thread will not be in stomach anymore. Perhaps give her more
oily food, like tuna in oil or some hairball cream to ease up the way down.
Grass is good too.

How long was the thread, exactly? I'd say anything longer then about 5
inches could be dangerous. If you can take a sample of the thread to the vet
as well. Hopefully she should pass it on , so do check her stools
thoroughly.

I wish you all the best. Please let us know how it all goes.

Gee

When it starts to come out don't pull it.  If it is out only a little
or half way, cut it off.  Watch for the rest and do likewise.

One other thing to watch for: if the string was long enough, Mollie might
have swallowed the two ends and left the middle hooked under her tongue.  If
so, it could be damaging the tongue -- if she lets you, look in her mouth
and see if you can see it.

Yes.. A string hanging out of Mollie's butt. DON'T pull it!

You're quite welcome, little lady.

We had a similar issue with Ginger, but it was with ribbon (from mylar
balloons).  We adopted her when she was 1.5.  I had 2 cats prior to
her, and never had one come near a ribbon. I had received balloons for
my birthday.  One day I came downstairs and the balloons were on the
ceiling, the ribbons had been chewed.  Ginger was not feeling her best
all day.  That night, she threw up technicolor vomit (ribbons!). From
that day on, all balloons entering our home have their ribbons removed
and replaced with string.  She has no use for string and leaves it
alone.  I hope your kitty is ok!
