I would of suggested a very warm cloth to loosen what’s clogged. Also, I would separate the kittens from mom now....let mom dry out(once unclogged) so that she can get spayed. Kittens need canned and dry kitten food now. And only water....
The kittens have been in Science Diet kitten chow for a few weeks now and lots of fresh water. They are thriving and are very healthy.
I think Mia needs them more than they need her :-)
The good news is as I am typing, they are all curled up next to me and Mia is letting five of the shuttles dock. (Little Jan is just conked out against my leg) And she is “smiling”, not crying.
