Jen, I know what you mean by their own tiem schedule! Though usually when Clover and/or Echo even think about considering beign brushed, it's in the middle of the night when they're beign cuddly and I'm sleeping.
Clover hates the brush, but she's too nice to even growl, which is really sweet. She just gets this hopeless resigned look whenever you catch her to brush her, and then tries to run whenever she gets the chance.
I've been brushing her for like fifteen-twenty minutes a day, and the hair still hasn't died down. Today I brushed off a baseball sized clump overall!

Oh my babies fur is SO FRIGGIN SOFT now that they're both dry after the bath last night! it's like... SILK!
