The cave became the target of enemies and most of its beautiful decoration was destroyed in the past, which was also a consequence of the fact that the planned opening of the cave never took place. Speleologists call it the "Stolen Cave". Kysacká Cave is one of the important wintering grounds for bats. Their protection is taken care of by the Bat Protection Group, which also organizes regular censuses of these flying mammals. 7 species of bats were recorded in the cave in Kysak. The most famous of these are the small farrier, the large farrier and the common bat.
