PS: no, Timber's ribs don't show like that. He is well fed, don't worry
As for Willow, well, he does look scruffy these days. He gets quite wheezy when he tries to purr, and he purrs when I brush him (not because he likes it, quite the opposite actually). So I don't brush him as much as I should.
I did manage a nice portrait of Timber later on, as he settled on his sofa.
