Samantha Garden was on her way to work in Lockerbie on Wednesday morning when she noticed the strange looking creature standing in the middle of the road near Hoddom Bridge.
The 22-year-old from Middleshaw claims it looked her straight in the eye before bounding off into nearby woods.
She said: Ive never seen anything like it before.
After it disappeared, I thought to myself did I really just see that?
It was about the size of a small deer or fox, brown in colour with white tufts of fluff at the top of its ears.
It had what looked like a tigers tail, which flicked up at the end.
Im going to report it to police just in case anyone else has spotted it and its on the loose in nearby woods.
Samantha isnt the only person to have spotted big cats in the region.
In January, Aaron Halliday and Nathan Crosbie spotted a big cat similar to a panther in a field near Dalbeattie.
And last year, three mysterious cat sightings were reported in the space of a month.
Dan Alexander, of Dumfries, claimed to have seen a creature on the A75 near Newton
