Cat prints? Not again...

It is now time to update on the hunt for alien big cats in the UK. Last time, you will remember I was told by a member on an invertebrate’s forum that her boyfriend had taken a cast of the print of an ABC, or so her other half’s mate said, in their local area. Naturally, I asked; “where is it now?” and the reply was “I don't think he has the cast anymore”. “Bugger!” thought I. Never mind, she sent me a link to a photobucket account where there were photos to look at instead. They looked like a good match for a cat to me and the size was well within big cat range. After forwarding them to Richard Freeman, I emailed Hollie, as her name turned out to be, who gave us permission to use the photos, and it is to her that I am very grateful for otherwise this extra evidence would not have come to light. The best photos are shown below.

Also, she said that her boyfriend (Dan) had “actually seen the cat one night when hunting up there, though it was it dark he says he remembers seeing a big pair of eyes, too big for any "normal" animal, and looked orange coloured apparently.”.

Now, it is time to explain this eye shine business. Eye shine is, obviously, caused by light entering an animal’s eye, reflecting out of the animal’s eye and then entering our own. The shine effect is from a layer of tissue called the Tapetum lucidum which is found in many vertebrate animals. Its function is to reflect light into the light sensing cells (Rod cells) in the eye to enhance night vision further. So, when a light is shone into an animal’s eye, you quite often see it shone back at you from their eyes as the light escapes from the lens and through the pupil. Carnivores possess a choroidal tapetum cellulosum which is made of reflective crystals, whereas artiodactyls and perissodactyls have a choroidal tapetum fibrosum made of extracellular fibers. So, these two different reflective layers give different eye shines.

Eye shine varies between different animals, but it is not an exact science. Cats usually have green eye shine (domestic), as do deer, but dogs can vary from green to yellow and to orange, depending on breed. However, a number of reports say that big cats like leopards have orange eye shine, which completely confuses the matter! I must say this subject has been hard to research; everything contradicts everything else!

Then, as if this wasn’t good enough, Hollie spoke to her boyfriend, who said that his mate still had the cast, and that we were welcome to have it for a bit! This is excellent news, so we will have to sit tight and wait for Pat.

In the mean time, Richard got back to me to say this:

“Though I will reserve final judgement until I have actually seen the cast my initial feelings are that these are indeed cat prints. The toes are asymmetrical and lacking in visible claws. The central pad lacks the concave shape of a dog’s .The toes also appear to show greater flexibility than a dog's.”

He attached the following photos; the uppermost photo is of a leopard, whilst the other is of a puma’s print.

Now compare these photos to the cast photos above. Richard says:

“It could belong to a puma or leopard but I think it is most like a puma's with the wide toe pads. In fact the print reminds me of a Florida puma print I saw that had been cast from a track left in sand.”

I agree with him, but also the central pad in a puma is more compact than a leopard’s, very similar to the print in the photo.

For a further analysis, we will have to wait for the print to be delivered. Watch this space with bated breath! But may I just say again how grateful I am to Hollie for letting me look at the photos and for doing her best to help find the cast. If only everyone came forward with evidence!

The cat came back

After me bemoaning the fact that there were less and less kills from this ABC in my area, it seems once again it is time to pop open a Beast (fear not reader, I will explain all).

Yesterday as you are all aware was Saturday, the day I fire up my car and zoom off to work to earn an honest buck in order to keep myself and beer as close friends. Now, the day was fairly unspectacular (other than the freezing cold conditions) until it got to around 1400, when one of the shotgun coaches said to the three people he had just been tutoring “Ah, here’s the chap you want to speak to.” as I wandered past. One of the gentlemen proceeded then to tell me that he had a big cat in his area (Taunton) and that it was killing sheep.

It had been through a fair few apparently, but the only bodies my contact had seen were those that the farmer had shown him after he had dragged them in from the field. The sheep’s pelt had been taken off the bones, and the only bones the farmer brought back were the spine, ribs and skull. Now, this proves very little (ie, was the killer a cat, canid or just an excuse) as the sheep had been moved from, what we would call in palaeontology, life position (you can think of it as being moved from its exact position of death). The sheep killed were all grown on lambs at about ¾ of full size.

This is very interesting indeed, and I have exchanged emails with one of the chaps who will provide me with photos when he can. I intend to get up there as soon as I can. This is probably not the same cat that I have been dealing with closer to home, but 25 miles away as the Raven flies (or as the Leopard runs for that matter) is, although seemingly large, not completely out of the question. Remember, an ABC in the wild would probably not have a territory this large, but this is not their wild habitat (with the possible exception of Lynxes). We have no idea how they behave when their prey is confined to a comparatively small area of land and are fairly easy to catch and kill. Will their territory size increase? My feeling is that yes it will do. Territory size is controlled mainly by two factors, how many competitors there are nearby, and how much food there is nearby. So, taking a Leopard as an example, lots of Hyenas and Lions around will diminish its territory size, and lots if easy to catch prey with a high nutrition value will again, diminish it. Few competitors and hard to catch, low energy prey (rabbits for instance) will both increase territory size. Note, low energy prey is prey that may be low in calorific content (or whatever measure of nutrition you want to use), but also take a lot of effort and energy to catch. For a Leopard of 80kg, a Rabbit which might get to 1kg is much more energy intensive to catch and eat than it is for a 10kg Fox, hence why Foxes take a lot of Rabbits.

Here in the UK, we can see a large amount of easy prey (expected to reduce territory size), but a low population density and little competition (expecting to increase territory size). I would expect with the evidence available to me that 25 miles for a territory is not as mad as it may at first seem for a Leopard/Puma/whatever. Just to err on the side of caution however, I would say that this is not the same cat.

Now, that lot is good for a day’s work. However, it gets better. I got home, showered, ate tea and then went onto the computer to write an article about keeping beetles for Exotic Pets magazine. I went onto an invertebrate’s forum, (on which I am the moderator of the beetles, aquatics and cockroaches sections) to check how things had been over the last day, and what did I find? Someone had posted a thread in Off Topic about big cats in Britain. Obviously I looked at it, and I was really surprised at what I found (I will not repeat the thread here, but you can go and look at it if you sign up as a member for Bug Nation).

The jist of the thread is that one of the forum’s members had noticed in the local paper (the Hastings Observer: http://www.hastingsobserver.co.uk/509/Bumper-year-for-big-cat.3674641.jp) that there were big cats in the area, and was wondering what people’s thoughts on them were.

Now, attached to one of the thread starter’s posts was two photos which her other half had taken. One was of a large paw print in some mud, and the other was of the plaster cast this person had made of it. This is a brilliant example of people (one wants to use the phrase “general public, but that would be a touch insulting) using their initiative, getting something done and helping us all out. Good job!

Unfortunately, I cannot tell if it is a cat or a dog, as although there are no claw marks, the back of the central pad is obscured by a lighter used to show size. The pad is the same length as the lighter, and the whole print looks to be about 1.5 lighters tall, within cat size. The digit pads are close to the central pad and are all of similar size. I have contacted the member to see if I she can get some better photos of it for me, and obviously, I will keep you all updated.

As for that thing about the Beast, well, it is a little tradition I have.

Whenever something big happens with my big cat research, I open a bottle of one of my favourite ales, Exmoor Beast (a superb dark ale with a strong chocolate and hops flavour) which depicts a melanistic leopard jumping toward the drinker. As proof of this being a good day for me, here you can see me drinking aforementioned beer...
