Anyway, the attention-seeking little fiend has contrived to develop a lower urinary tract infection. She arches over the litter-tray with a look of serene expectation, stands there for a little while, looks down disappointedly, paws at the litter, ambles off. Ten minutes later, she repeats the performance with a mounting expression of feline consternation. I remember this routine, and it has its sequel not in the litter-tray but on my duvet.
