West used to import exotic animals but lost his licence several years ago when he brought several lion cub from a private zoo. Later on, he appeared to be breeding dogs for fighting.
When a rogue Smilodon attacked someone at Blue Sky Park, Nick Cutter and Jenny Lewis investigated West's farm but he asked them to leave after showing his dogs to them. Jenny later blackmailed West to admit he had been keeping a lion (to cover up for the big cat) because of his dogs but West refused to be "stitched up". He then grabbed his shot gun, taking Jenny hostage but the Anomaly Research Centre team arrived and saved her. They then let West go when they relised he had not been keeping the Smilodon.
