@msolga,
Why, thanks, MsO; the knees hold up well -so far. Do note, though, Miss Molly's position of vigilance -- being the ever dutiful cat. Before settling on my lap, however, both of them get a sniff at my coffee. And Nekochan, being senior cat and house matron, gets first choice of seating.
It's the usual morning routine here, weather permitting .
