Ruby made her first trip to the groomer in months today. Her claws were trimmed and a metric ton of undercoat was washed and brushed away. This explains what I've been sweeping off the floor. The *huge* piles of undercoat that I've been sweeping off the floor.
Anyway, Ruby looks much better. And her paws are no longer lethal weapons.
Her R-factor is substantially reduced as well, which is good, given the weather outside.
