I've got a maine coon (just 1.5 years old) and she's a real sweetheart - but for the want of trying she will not let us cut her claws or brush her. She absolutely hates anything to do with grooming - grooms herself to the minimal level.
I've had cats before and this is my first time encountering so much resistance (and she has no interest in food beyond what is necessary - so we can't distract her or bribe her).
She lets us touch her when she wants (she might jump on me and force my phone out of my hand to stroke her etc) so while fussing over her, I've noticed the inevitable matting starting.......and it's grown into what must be an uncomfortable mess for her.
As matting can pull the skin and cause actual problems, and a regular groomer can't handle her (she's scared of strangers) we called vets requesting that she be mildly tranquilized and shaven - they all rejected saying that until she's got an actually injury or infection from the matting that it's not important.
My hubby and I didn't want it to progress to that, so for the last month I've been stealthily following behind my cat on my hands and knees with some scissors, cutting the hair back until we got to the matted layer, and between her licking and my cutting we've got almost all off and her skin looks fine.
So now she's got a little hair on her body (but not a lot) and, in short, as it grows back, any advice on how to not arrive at the same situation again?
