Go bag list. Am I missing anything?

Hi y'all I'm preparing a go bag just in case because I feel very vulnerable without it.

I'd say I'm an aspiring prepper, once I have more money I would feel more secure and able to buy the kinds of things I would need to be prepared to lock in at home. Right now I could last 72 hours definitely, probably a week if I had to. Luckily I live at a relative's house right now and they have a generator, so at least I'd feel secure if there were a power outage. But honestly I'm woefully unprepared and lack the survival skills I might need in a more extreme situation. This post isn't about survival skills, but if you do have recommendations for where I can start on that I'd appreciate it. I have read through the new prepper's resource guide and plan to read "Countdown to Preparedness" that was recommended there.

For the go bag, it is just myself and my cat. I will be keeping this in my car. I am going to shop tomorrow for anything I don't already own that is on this list. Here's what I have on my list. Am I missing anything major?

  • batter-powered radio
  • beacon/locator light
  • blanket
  • bottled water
  • can opener
  • cash (grab this on my way out so not too much cash in my car)
  • change of clothes
  • collar for cat
  • compass
  • deodorant
  • dust masks
  • extra batteries
  • extra litter
  • emergency thermal blanket
  • first aid kit
  • flashlight
  • food/water bowl for cat
  • garbage bags
  • glasses
  • hand sanitizer
  • hand warmers
  • harness for cat
  • headlamp
  • important documents (for myself and my cat) (grab this on my way out)
  • jacket
  • knife (mine has a window breaker and seatbelt cutter as well)
  • laundry bag
  • life straw
  • lighter
  • litter box (grab this on my way out)
  • local maps
  • brush for cat
  • anti-anxiety for cat in case
  • matches
  • multi-tool
  • pain relievers/etc
  • paper & pencil/pen
  • paper plates
  • paper towel
  • pet food
  • phone charger
  • pictures of family members, picture of me and my cat
  • plastic utensils
  • portable charger
  • prescription medications
  • rain gear
  • scissors
  • shampoo
  • snacks/food
  • tent
  • toilet paper
  • toothbrush/paste
  • water bottle
  • water purification tablets
  • whistle
  • body wipes
  • woolite (laundry detergent for hand washing if necessary)

Thank you for your help.
EDIT: To clarify, the bulkier things like those for my cat will just be in my car always, they won't be directly in the go bag
