A pill box with Benadryl, some herbal calming pills (LOLOLOLOL those are worthless I don't even know why I still have them), Traumeel, and Pepto tablets
Rescue Remedy
Thermometer
Vet wrap
Alcohol wipes
A couple gauze squares
Bandaids (for me)
A couple baby socks
A muzzle (Auggie and Pepper size, it won't fit Payton but I suppose might do in an emergency, which is what it's there for...)
Saline eye wash
Vaseline
Antibiotic cream
A small eye dropper
A larger eye dropper
A small collapsing water/food bowl, it folds up teeny tiny and flat
I think that's it. I too keep meaning to add some hydrogen peroxide to mine and haven't. =P
