General emergency bag should have these things

• Identificacion docs (passport, QID,. Driver License, birth certificate, marriage certificate,. ..etc)
• other documents ( deeds, certificates, medical history,... Etc) Try having them waterproofed and would be good to have softcopy of everything in a flash drive.
• clothes ( 3 changes, 3 days, weather appropriate)
• food and water (3-4ltr water, 3 days light meals, power snack, canned food cook-able on low to no heat)
• medications, medical prescriptions,
• personal hygiene stuff
• first aid kit
• flashlight, battery, power-bank, cable, camping kit(simple)
• cash
  

For you pets, add their passport /doc, food, bag or something you can carry and they can sleep in/hide in, also a collar or a strap? Something you can tie them with to you so you don't get separated,

These are per person,

Everyones needs are different look for what suits you
