I have had two cats in the past.( Simon and Amber) both who would hear the vacuum, seek me out and plop down right in front of the machine and refused to budge an inch until each had their turn being vaccumed. I never had to brush either cat, I vacuumed loose hair away .
Every other cat I have had has run from the sound of the vacuum, but these two furry oddities LOVED their personal grooming tool.
