I have a backpack for my cats. I'm disabled and it makes getting to the vets easier than trying to manoeuvre a cat carrier and my frame.
Today I decided to surprise the children and took one of the cats on the school run 
He was very happy and the DC were well impressed. Well, except DS1 who is 13 and got home before us and began panicking that we'd lost a cat until he phoned me and called me nuts when he realised what I'd done.
So
YABU - you've lost it woman, get some help
YANBU - it's a genius idea
