Thanks for all your healing thoughts.
Turns out Mittens had bladder stones that had to be removed immediately.
Now she’s back from her four day stay at the vet.
Poor girl has to wear this collar for a couple of weeks and is now on a special diet (forever). I thought I was feeding her quality food but …
It’s a good thing we caught the problem when we did and she’s now on the mend.
Seems as if Sophie forgot she has a sister so I’m running around trying keep them both civil.
