What do you keep in yours? What do you feel is indispensable and what do you wish you hadnt bought? I'm looking to put together a decent first aid kit without lots of unnecessary stuff.
vet wrap by the bucket load.
square animalintex poultice (if you have a foot absess just cut it to size)
roll of cotton gauze
nappies and duct tape (for dressing foot absesses)
thermometer
wound power
sudocreme
bandages (old tail bandages work well)
scissors....
tub of table salt
tea bags (cold (black) tea is great for washing eyes with)
That's what I have in mine. most of it can be bought from boots which is much cheaper than any tack shop!
