Alberta cattle mutilations
From August 1979 ranchers around Calgary and across southern Alberta reported cattle found dead with organs and tissue neatly removed; police counted dozens of cases by mid-1980.

The account
The RCMP investigated and in 1980 publicly suggested a cult might be responsible, though no one was charged. Reports continued sporadically into the 1990s and beyond on the Prairies.
The sceptical view
Veterinary studies elsewhere found that scavengers, insects and bloating produce the 'surgical' look. No case was solved as a crime.
The researched reading
A wave of strange-looking cattle deaths. Scavengers and decay explain most, perhaps with a few deliberate human acts.
| Explanation | Weight | Why |
|---|---|---|
| A known natural phenomenon | 50% | Carcasses left in the field are scavenged at soft tissues (eyes, lips, udder, genitals) by birds and insects, and bloating and skin shrinkage make wounds look surgical; veterinary studies in the US found the same. |
| Undetermined | 17% | The share the reading had given to fabrication on doubt rather than evidence: the record does not settle it either way. |
| Perception, memory or mind | 12% | Once a mutilation wave is reported, ordinary dead cattle are reinterpreted as mutilated. |
| A hoax or fabrication | 5% | Some cases may be deliberate acts by people, including pranksters or copycats; the RCMP considered a cult, though none was found. |
| Something known, misidentified | 5% | Some cases may be misjudged natural deaths. |
| Secret human technology | 5% | Secret sampling for diseases or radiation has been proposed, without evidence. |
| Genuinely anomalous | 4% | Nothing found requires a non-human agent. |
| A poorly understood natural phenomenon | 2% | No unknown natural cause is needed. |
Official position: The RCMP investigated and suggested a cult might be responsible; no one was charged.
