I keep all the dog & cat supplies (grooming, medical, etc..) in a small rubbermaid tote not too far from the door.
All the leases are hung right by the door.
Cat/ferret carriers are in a closet right next to the door.
Poop bags, a dog first aid kit & extra collars in a tote bag hung next to the door.

I admit, right now I am slacking, their records are in a folder (all nice & neat) but it is in a spare bedroom. Thanks for reminding me that I need to move those to a more readily available location. I should also print up some new pictures of them all to add to that folder.
