Loving Mabel & her camera poses OP, especially the one where she's flat out on her back :)
My Jake is long haired, all be it a normal moggy not pedigree (genuinly not sure if there's a difference in the coat texture)
Had to have him shaved down by a groomer when i first got him (traumatised both of us due to noisy clippers & horrible attitude of groomer)
Anyway, he likes having his back, sides, chin & bib combed now but to get to the belly i have to wait until he's sleeping flat out on his back, even then it's touch & go as to when i'll get my hand mangled, that's to say nothing about the err, derriere area - it's a two man 'pin him to the floor' job in diarrhoea emergencies.
No easy answers, my local pets at home groomers are very good so take him there for any baked in 'dangle berries' & he doesn't seem to mind too much.
I also keep almond base oil on hand - spread on hands lightly (very little goes a long way) & stroke cat wherever you can reach without losing a limb :)
Makes the coat very easy to brush & untangle - word of warning though - mine adores the taste of the oil, licks my hands & himself to get as much as possible.....still, while he's busy licking i can get a few belly & underarm comb strokes in unnoticed :)
