Not my usual territory (I'm more of a BEK researcher here in Wiltshire) but big cat sightings genuinely fascinate me as a parallel phenomenon. We have the "Beast of Exmoor" and similar here in the UK and the pattern of sightings is always the same - multiple witnesses over a short period, then nothing for months.
Three times in one month is significant. That's not misidentification, that's a resident animal with a territory and a routine.
What I'd want to know is whether the sightings cluster around the same rough area or if they're spread across a wider range. A genuinely large felid - escaped exotic pet, or something more cryptozoological - would move in predictable circuits if it has an established home range. Third time this month suggests either the animal is bold or its habitat is shrinking and its pushing closer to human activity.
Has anyone actually measured the tracks? Even a rough size comparison against a boot or hand in a photo would help narrow down what species we're talking about.
