I have five cats and getting them to the vet is a real chore.  Taking them out of the carrier was even worse.  I had to dump them out like a sack of potatoes.  But this carrier is so so so easy.  I just pick them up and put them and close the door.  Open it to let them out.  That's it!  It folds like a briefcase to store.  Oh and my big 17 pound fat cat fits nicely.  The only down side is the color.  I wish there was something a little less drab.
