The B-C Environment Ministry says three cougars were destroyed after killing a lamb and attacking a donkey at a rural Comox Valley property. The ministry says a property owner called R-C-M-P to report the deadly cougar attack over the weekend. Mounties arrived at the property to find two cougars thought to be juveniles still on the premises and killed both of them — but suspected an adult cougar was still on the loose. Conservation officers arrived at the property with tracking dogs early Sunday morning and eventually located and killed the adult cougar.
