However, not all hope is lost, you've thought of the greatest solution to this epidemic of cute and cuddly creatures. 


You've got enough fuel and fury to slaughter them before they can reproduce. You're not alone either, Uncle Jon is ready to slaughter some vermin and aid you in any way he can to increase your furball extermination efficacy.
