Lol, he loves the noise for sure!! Mallorn also loves the noise but she hates actually having the vacuum close to her.. she also loves my hands. So! There's that LOLL.
It's so great that you're so wonderful at picking up on your boy's body language already. I have a similar ritual when picking up Mallorn's cage because while she's very strongly bonded to me and my family, she can be a little bit skittish, so i always say "You ready?" and then count to three before lifting her. Her cage is bigger than it was when she was little so I don't do this as much as I used to, but she definitely liked those little routines we had.
