Both cats were stolen off my daughter's Tacoma last Christmas eve. The solutions I researched then included welding a rebar or cold-rolled steel cage around the cat, or even welding steel straight to the in & out flow piping adjacent to the cats. The idea is that the piece of shit crack head thief will have to cut through at least one or two or more pieces of the heavier steel to either physically access, or physically sever the connections and remove the cat. This will take much longer and may also require a blade change during the thievery process. In most stock configurations, the piece of shit crack head thief can have a cat out in under 30 seconds.
