My last Pema update was nearly two years ago, and I said that our previously semi-feral cat was near to discovering laps-- optimistically, as it turned out. Because she only became clear on the concept within the last couple of months. And of course, she now owns it.
I think it may have happened because we got rid of our old couch before we got a new one, and substituted two chairs for the ritual evening DVD/recorded TV show hour. Suddenly she had nowhere to sit. She was comfortable sitting behind Margaret on her chair at the kitchen table, but that didn't work in the living room. So that's probably what led to Pema's discovery of the lap.
First Margaret's, then mine. She favors mine at the moment, probably because it's easier for her to jump up to and jump down from my chair, and because Margaret is often knitting, while my hands are free to be dedicated solely to Pema. Though it took her three years to discover laps, I now barely am seated before she jumps up on mine.
Pema goes outside and has learned her circumscribed permissible area--mostly where she's visible from the back door. She's a bit more curious about other people when they're in the house, though she tends to reconnoiter quickly before retreating to her safety zone. Otherwise, she's retained some curious ways. She still won't drink water, except as part of a soupy mixture with soft catfood. And when her soup dish is picked up for filling, she still goes out of the kitchen and sits under the dining room table (she is never fed anywhere near there) for reasons still mysterious to my poor human intelligence.
The next step is for Pema to get comfortable being picked up. She's a little more relaxed about it now, but she still won't allow herself to be held. Tess didn't like it much either, except by me: she liked to rub her head on my beard. I don't know about Pema. Maybe by next Christmas.
