i have 2 piggies that are really having problems one has what i now know to be a large burst sebacous cyst about the size of a 2pence peice the vet wants to remove it at a cost of £100 (i don't have that kind of money!)the cyst has left a large crater the edges of which can't come together the second piggy has a large abcess that has burst and is sore and despite draining and flushing is looking really horrid i'm using diluted hydrogen peroxide as instruted on the peter gerney site both piggies are eating and i am giving them baytril i may have to have the one with the cyst put to sleep i really don't know what to do i have kept guineas for years but never had such problems
