My guess, sleeping.
This morning, she went back to the SPCA. It’s lucky that she had an appointment since they are at capacity now.
She was a brave girl and went into the new crate with no problem.
I will miss her.
But I can only hope that she will get adopted into a home where she can roam around, sit in a window in the sun, watch tv in the lap of a loving owner, and have her sweet cry answered with dinner.
