Why resist the irresistible

Sylvester (the black-and-white) and Gary (with stripes) have never been able to resist what I call the "crack sweater," because they respond to it so strongly. Indeed, they're the ones whose constant kneading has caused it to look so shabby.

The book I'm reading on Kindle is Margery Sharp's Something Light. Just discovered her after a mention in the Sunday NYT Book Review. Very good mid-century English comic writer; she's been compared to Barbara Pym and Elizabeth Taylor (the novelist, not the actress), but also has what's almost a touch of Wodehousean absurdity.
Eventually the babies (as we still call them at age 6) settle down, but it still makes reading a bit more challenging.
