Species like this seem to have some kind of focus-deflecting abilities so that photographs always turn out blurry and indistinguishable from a large feral cat.

Species like this seem to have some kind of focus-deflecting abilities so that photographs always turn out blurry and indistinguishable from a large feral cat. They weren't silent animals either, and were fond of raiding sheep, chickens etc., from farms (the reason they were exterminated). It doesn't seem plausible to me that they'd survive with such a low profile for circa 90 years.
