How much and what emergency supplies to keep on hand for elder?

I was just curious as to how much and what emergency supplies others keep on hand for their elder. My husband thought I was nuts because in Sept. I bought about $1000.00(I know a lot) of supplies like paper towels, toilet paper, bottled water,commode liners, kitty litter for the commode(great for odor control and to solidify liquid waste),Clorox,the brand of dog food mom's dogs eat,doggie pee pads,several 40lb. bags of rice, several cases of beans,soap,detergent,soup,2 cases of Assurance diapers(this would be 400 diapers, mom goes thru about 5 a day). I know I sound like a doomsday prepper. However, at the start of Oct. I came down with an allergy/cold or something and I was sick and practically bedbound for about 4 weeks, also with winter coming my main access to a Walmart is on an interstate that has several bridges that ice up(black ice) during the winter and I really don't want to run out of diapers.So I was wondering, do you guys think I am nuts or what?
