On this web page I should like to place information about possible medical treatment of snails.

  The severest problem with snails’ health I confronted with was the destruction of a shell. Such destructions can appear, for example, if snails fall to the ground.
  If only the edge of a shell is damaged, even very hard, a snail itself rather quickly restores it. Such damages are not dangerous; only further, on this place on surface of the shell there will be a roughness (strip).
  It will be much worse if the shell is punched closer to top. The snail itself cannot restore such damages.
  It is absolutely bad, if the shell is completely broken.

Snails’ shells jobbing

  All manipulations should be carried out with observance of cleanliness and accuracy.
  Clear the damaged place of dirt and particles of the broken shell. If soiling is strong, wash this place out, carefully immersing a snail in water (+25-30 degrees Celsius).
  Cover this aperture in damaged shell using thick plaster and suitable (plastic or metal) an elastic plate. Do not try to do a layer of plaster too thick and do not push it inside because it can squeeze internal organs of a snail. Remove the surplus of plaster.
  The shell must be dry and clean during the whole period of restoration lasted.
  In 2-3 hours after hardening and drying of plaster, put on plaster and a shell around it a layer of correctly prepared epoxy resin (glue). I used epoxy resin "EDP" (Russian name).
  It is the most tiresome part! Don’t let epoxy resin contact the body of a snail. Note, that epoxy resin dries up during long time and also trickle down. Probably, you’ll have to rotate a snail, slowly and cautiously, and carefully wipe up epoxy resin. In some hours epoxy resin will lose its fluidity and will start to harden. While epoxy resin remains fluid, it is toxic for you and for a snail (see the instruction to resin)!
  In 6-7 hours the snail can be placed in a separate terrarium with small humidity and without capacities with water.
  In a day epoxy resin will harden completely, and the snail can be kept as usually.

This is a top of a shell after restoration:
1- the aperture is covered with plaster, under a layer of epoxy resin, 2- hardened epoxy resin.
On the right - the same snail, after half a year.

  I successfully restored snails’ shells damaged closer to top. All snails, after the restoration procedures are alive, healthy, they grow and breed already about one year.
  Dried up epoxy resin is nontoxical, hold on properly and abrasion resisten.
  Probably, this or similar method can be applied in more complicated situations, which fortunately did not happen to my snails.
  It seems to me, it’s better not to use plaster if damages are big. It is better to try a foil, a tin and a wire, plastic. Then to cover them by epoxy resin or cloth impregnated with epoxy resin.
