Always have a two week supply of your pet's normal food on hand plus some additional canned and dry food (in case you come across other pets in need). Keep an emergency water supply on hand for your pets.
Keep your pet's licence current and make sure a collar identification tag is worn at all times. Consider having your pet micro chipped or tattooed for quick identification of owner.
Train your pet to enter its carrier at your command. One way to train is to feed treats in the carrier and sound a bell at the same time. Repeat this process for several days. Continue to do this routine often enough to keep it fresh in your pet's mind. This will prove very helpful in locating a frightened pet. Train your dog to come on command.
Have the contact info for local animal control agencies and SPCA, and pet boarding kennels on your emergency contact list. Also, a list of pet-friendly hotels will help in case reception centres and group lodging do not accept pets.
Get to know your neighbours and their pets. Make sure you have contact information (daytime, evening and emergency) for everyone and make sure you have talked about appropriate arrangements for caring for each other's pets if something happens while you or your neighbours are not at home.
For pets on medication, store a two-week supply, remembering to follow your veterinarian's instruction regarding storing medicine.
A litter box for cats and a supply of cat litter, grooming brush and pooper-scooper; transport kennel for a dog or cat (there are collapsible wire cages and soft-sided carriers if you are short on space), pet beds and toys.
Create a pet file which includes veterinarian contact information, copies of dog license, vaccination records, contact information of friends who may be able to house your pets for short periods, a recent photo and other identification information.
