fek me russ something you know nothing about,lol.well here gose you will need at least 4 to 5 ferrets small ones,that meny cos some just wont work rats,if you carnt dig them dont put it in with the rats as they gang up on your ferret,seen it meny times 3 rats hold of one ferret!if you can dig to them use ferret but be quick to dig to them,you carnt use a collar cos it restricks the movement of the ferret in the fight,yes russ fight your ferrets wont last long ratting,carry antibiotics or pen,tabs after the ferret has been bite which it will,open tabblet pour a bit in your hand nd spit into it
