RE: Memory retention of animals?
if they just get a wif of something not right they will normaly just give a huff/whease sound and be off and will come back if its thier travel area.But if thier tail goes up and they bolt out thats when they will realy scent a area to warn others not to come into the area.
if they lift thier tail huf/whease alittle they normally dont scent out the area.
They have to feel a threat......
