Good post , I was actually thinking about the same thing recently ..
Perhaps some heat/cold packs in case of power outage, polysporin/neosporin(without pain relief) ..... and that's all I could think of lol , looking forward to seeing what others have to suggest though.
I would think some contact info for the nearest (reptile) vet (in case you have a friend watching the reptile in question). I also think ig it a large neough kit a large sterile towl or a tub set up as sterile as possible. so can be used to keep the animal question in and safe.
I think I got a semi ok set up i got the neo, some sterile medical supplies form first aid kits. I am goingo t get some of the sterile suture kits( since I'm pretty sure I can stich up a snake if Ican do myself (I use superglue on myself cause most the time it hard to do stichs with only one hand lol.) I also got a couple handwarmers, I looking for a vista card I can stick in there and keep addign funds for that won't expire if left un used. this would be my snake emergency fund/card )Ieither that or a bank account with a debit card strickly for the snake related issues.
