Another Perthshire Big Cat

From Big Cats In Britain, a further sighting of what is presumably the same animal mentioned on previous post:

"06/09/2010
Aberuthven. Behind houses in fields.

Jet black, blacker than black, chasing roe deer.
Pointed ears
This is the strange part I can't remember noticing the tail.
Same size as roe deer but longer in length.
250yrds down field, from my house.
I was just up and standing having my coffee and went out to have a cigarette on my decking and I always look down the field when I saw roe deer running away from this jet black creature, at first I thought it was a bear, but it ran into woods on all four!
I am more vigilant. I have been down field with my dog looking for prints, thats's how sad i have become!!"

Aberuthven is a village on the road between Perth & Stirling, close to Auchterarder, and just north of the Ochil Hills, which places it in the same general area as the previous couple of sightings. I'm fascinated by the recurring description of the cat being bear like, this suggests quite a heavily built animal (though I admit I'm mildly confused by the witnesses statement that they thought it was a bear until it ran off on four legs- does this imply it was on two legs at one point??)
Edit: having just reread the previous sighting, they sound pretty similar, so they could possibly be different accounts of the same sighting.
