Loving the cat behaviour expertise on here. Haven't ruled out hyperthyroidism, but she's less than 2 years old. Would it be possible?
As she settled a bit, (mostly only angry with me, it seems -- she can smell my fear) we haven't brought her back to the Vet. We'll see how the next few weeks go. She is certainly territorial at times, but she also wants to be around us -- she follows us and rarely stays on her own anywhere except when she's sleeping, and at night we can see she's been in our room as we find her soft fluffy balls in the room. And oddly, her favourite space isn't up high its on a cushion on the floor.
I'm really really really missing my kind loving Burmese cat who died early last year
