I'm interested in this. As a veterinary pathologist I occasionally have to investigate livestock deaths involving teeth-marks. Last year we had a spate of stuff happening near here, including two ewes with their throats torn out, a lamb with a fatal bite to its flank, and a young ewe with a huge lump taken out of one leg. I wish I could post a picture of that last one because it was very dramatic, but it would probably be judged too gruesome. Of course we thought about the "big cat" possibility, and indeed one of the ewes was brought to us by a policeman with that specific question.
However, the conclusion was "big dog". In each case the bites were more typical of canine jaws. Also, the
modus operandi was almost always a single bite, with the carcass found otherwise unscathed - that is, not actually eaten. The ewe with the leg bite and two of the lambs were still alive when they were found, and in one case the perpetrator appeared to have run wild round the field killing several lambs but then abandoning the carcasses and moving on to catch another one. This had all the hallmarks of an animal that was not killing to eat to live.
The number of carcasses brought in with significant amounts of meat missing was exactly zero. In total, though it was enough to get concerned about, there were only six or seven incidents over a period of many months. My conclusion was large domestic dogs intermittently sheep-worrying.
If there is a feral big cat, or even more so, a breeding population, I want to know what they're eating. I absolutely accept that some carcasses might be completely scavenged and disappear, but central Scotland is a well-farmed area and farmers do know how many sheep and lambs they have. Nobody has reported unexplained disappearances. Even if some carcasses were completely disappearing, I would expect at least
some to be found part-eaten. It's the law that all livestock have to be inspected at least every 24 hours, and most farmers comply with that (and then show up here with the casualties when I'm already busy....)
We did have one strange case where a set of sheep bones was brought in, however these were clearly the work of human hands, with bones having been sawn and meat sliced off cleanly with a knife. They'd been lying around for a while, but weren't much gnawed, showing that a stripped carcass doesn't just vanish without trace.
Sheep and lambs are very vulnerable to this sort of predator. I fail to see how something like that could live
entirely on wild animals, small rodents and the like, and if it ever does get a lamb, then somehow the carcass vanishes entirely leaving no trace. I'm really pretty confident that there's nothing like that living wild round here, because the evidence just doesn't stack up.
Helensburgh? There's more scope round there because it is on the edge of some relatively wild country, but my reservations above still apply. All the land is farmed, with sheep and cattle, and even the hill sheep are shepherded fairly closely. Farms which do have a problem are not slow to shout about it. Further north, some farms lost a lot of lambs to Sea Eagle predation this year, and there were articles in the farming press and bitter recriminations against the Sea Eagle conservationists. I have enormous trouble believing that the farms round Helensburgh are supporting a puma, and nobody has noticed any untoward losses.
There has been some speculation that the animal is a Labrador, but I saw the film on the TV news and I don't think so. The way it walks along the actual rail is not canine, it's feline. I just agree that it's probably not that big.
All-black specimens of the big domestic cat breeds are unusual, and most of these are long-haired. I
think the picture is of a shorthair. Scottish wildcats are tabby. My first thought when I saw the film was the same as most people here. Big black mog.
I had a similar experience a few years ago when cycling by a canal. I looked across the canal at an open field, and seemed to see a black panther walking across it. I did a double take, and realised that it was just an ordinary black cat, not even especially huge, but sufficiently far from any clear size comparison markers that I'd been misled. If the cat had vanished after my initial sighing I could easily have been left with the impression I'd seen a panther.
I think the size comparison markers in the video are deceptive. It's a single-track railway (though probably normal gauge), and it's not as wide as it looks. Even watching the clip, sometimes it did look like a normal cat. I think the position was just conducive to a bit of a
trompe l'oeil effect.
Domestic cats (which it probably was) have a fairly small range. I would suspect enquiries round the area would turn up someone with a big black pet cat.
Now,
about the horse. A few days earlier, a horse was found mauled near Ayr. Some "expert" said they thought this was the work of a big cat, probably a puma.
I want to know what the "expert" was smoking. (Actually, I'm guessing about the identity of the expert, but I think he may have been the guy who declared that an obviously dog-killed hare I'd examined might have been hit by a car. Yeah, a car with teeth? So yes, vivid imagination at work perhaps.) The same thing applies, only more so. The Ayrshire countryside round there is intensively farmed. And, this is the biggie, our Ayr investigation centre is only a few miles from where the horse was found. I flat guarantee that if farmers round there were experiencing livestock losses suggestive of a big cat on the loose, we would know about it. The only possibility would be a recent escapee, and I sort of think something like that might have been reported missing.
And just to squash the conspiracy theorists, Ayr isn't that far from Helensburgh as the crow flies, but it's quite far enough to make the two incidents entirely unrelated. Especially as there is a sizeable body of water separating the two places (the Firth of Clyde), and the only way to get across is either to cross the Erskine Bridge or trot right through Glasgow city centre.
The puma thing was just someone with a vivid imagination not thinking clearly. For goodness sake, just phone Auchincruive and ask if there have been any other suspicious livestock losses in the area before you come out with that one, why don't you? And the video clip was a big black mog.
