One word - Don't.
I should probably add some detail here, huh? Grace, my cat, is a 14 yr old DLH (Domestic Long Hair). I've always been lucky that she hasn't had issues with matting but lately, my luck has run out. I know it's getting harder for her to keep herself clean and the upshot is she is getting a lot of mats. She doesn't like to be combed or brushed out so the only option is to cut the mats out. That's not a big deal if it's a mat here or there but in the last couple weeks it's become more of an issue than that.
I already spoke w/Dr. Hillary about sedating Grace and shaving her but, hey, it was a long holiday weekend and I am a DIY kinda gal. I have an electric clipper so why shouldn't I attempt this on my own? Number one reason? The electric clipper I have is designed to shave out paw pads on dogs, not shave down an entire cat.
Grace now has a big bald spot on one side. This morning I went after some more mats with my thinning shears. So, basically, Grace looks like a drunken groomer got a hold of only one side of her. Thank goodness it's the side she usually sleeps on!
When Dr. Hillary gets the clinic open, I'll stuff Grace into a carrier and run her down there to have everything evened up. In the meantime, someone should probably take my scissors away.
