Kimmy has phantom pregnancy

Kimmy thinks she's pregnant (or even that she had puppies!). She collects her squeaky toys and brings them in her bed and lays down with them and licks them as if she would puppies. She whines when she can't be with her "pups".

She seems withdrawn and somewhat depressed. Subdued and just taking care of her imaginary pups.

When I take her for a walk, she is back to her normal happy self, though. Finally it cooled off a bit here so we can go out during the day without risking heat stroke.
