Would that be a lot of extra stuff for the "in case" scenarios? In the event of needing to evacuate could you drive far enough away to have access to unaffected towns and maybe there purchase things such as gauze if needed? Table salt (which is free in many public places) and (clean) water can be used to flush a wound (if really necessary) to clean and kill bacteria but hopefully nothing so dire would happen to the pets in their temporary homes on the way to a safer place.
Also, I totally agree with the warning about the 40 hour heat packs which is one of many reasons why I think a temp gun should be part of the emergency pack.
