Thanks to all who have commented. I am now, based on your helpful comments, leaning more towards just freeze dried meats, veg, fruits, cheese, butter and regular dried rice, regular pasta, mashed potatoes (we absolutely LOATHE beans/legumes). Mountain House scrambled eggs with bacon and the beef stroganoff had great online reviews, anyone concur?
You can buy freeze dried pasta/rice/potatoes, but not sure if it is necessary if properly packaged in mylar/O2 eliminators; anyone know about this? Same with dog kibble, animal feed; would the mylar +O2 eliminator make this stuff stable, long-term?
Where we live would not flood, and I suspect we could easily withstand earthquakes. It is access in/out that could easily be affected, so supplies such as food/feed for the critters and us our biggest concern. Because of the animals (sick, injured, orphaned wildlife), evacuation is exceedingly difficult. We have a bug out location, 7km away if staying is impossible or otherwise not safe (evil humans), complete with temporary small caging and pens, stored water etc. I would rather not have to capture/move patients during a natural disaster, or keep them for weeks in tiny enclosures.
Ideally both home and bug out location would be stocked for a solid two weeks of necessities: food, toiletries, water, bedding, clothing, foot wear, outerwear, cleaning supplies and medications.
If it weren't for our wildlife patients, then most of this would not be needed, but we are, unusual, and unlikely to be welcomed in a shelter. Soooo, preparing for the worst case scenarios is just something we've got to do.
Thanks for all the help so far, here's hoping there is more information to be gleaned!
