All Scottish wildcats and kittens should be DNA tested for purebred status

NEWS AND OPINION: There is a nice story about Scottish wildcats today reported by the Daily Record. It concerns three Scottish wildcat kittens at the Five Sisters Zoo in West Calder, near Livingston. On their first medical they discovered that they have two boys and one girl. They look very much like Scottish wildcats with their tabby coats and slightly fierce appearance which is exactly the way you want it. The photograph on this page is from the Daily Record. There next job is to name them and they are looking for suggestions on their Facebook page.

The report states that there are an estimated 35 Scottish wildcat in the wild in Scotland and that they are 50 times rarer than a giant panda. They may actually be rarer than that. In fact, they may no longer exist in purebred form. There's been so much interbreeding between domestic and feral cats and Scottish wildcats that it is plausible to argue that there are no purebred Scottish wildcats left in captivity or in the wild.

I don't know if any wildcats in zoos are purebred, such as these three darling kittens. I think that zoos should confirm to the public that they are genuine Scottish wildcats with no dilution of their DNA through crossbreeding with non-purebred Scottish wildcats.

Where a wild cat becomes extinct or is becoming extinct through interbreeding with other species of cat, it is beholden upon zookeepers who are in the business of conservation, they state, to make sure that they are caring for the genuine item and not a hybrid. For all I know these beautiful kittens may be hybrids and if they are you can't call them Scottish wildcats. One issue is that the appearance of a Scottish wildcat hybrid is very similar to the genuine article.

I don't want to be too negative because it's a nice story but I've seen quite a lot of estimates as to the number of Scottish wildcats left in the wild over the years and they are just that: estimates. This leads me to believe that there may be none left which is a stark realisation.

Although people refer to this species of wild cat as a "Scottish wildcat" it is possibly or probably fairer to call this cat a European wildcat. I don't know whether it is true that there is a subspecies of wildcat called the Scottish wildcat. 

Also, please note that I use the word "wildcat" and the phrase "wild cat" for a specific reason. The phrase "wild cat" refers to any individual cat of any wild cat species whereas the word "wildcat" in my opinion refers to the species which is the 'wildcat'. It is complicated but I'm being particular about this.

Are tigons fertile?

Tigons are a hybrid cross between a male tiger and a female lion. These are man created - correction person created (I don't want to be sexist although it is always a man who does it) - wild cat hybrids. A lot of private zoo owners in America like to mess around with ad hoc big cat breeding to entertain themselves and any customers who wish to pay money to see their miserable establishments. 

There are a lot of private zoos in America but they've been tarnished and discredited by Carole Baskin of Big Cat Rescue (BCR) who has exposed them for what they are: seedy, exploitative businesses where young big cats are exploited and where their parents are disposed of when they are no longer financially profitable. Enough of my distaste about private zoos in America.

Picture in the public domain.

Read another post on the same topic with more detail if you wish

The answer to the question in the title as to whether tigons are fertile or not is that the female is often fertile but the male is invariably not fertile. There comes from Sarah Hartwell who is an expert and I trust her implicitly. Other websites and other experts say different things. The Smithsonian Magazine say that they are fertile and that second-generation hybrids are created from first-generation hybrids such as the tigon and the liger. And yet another website said that they are infertile. Clearly there is some disagreement but it seems that it's a grey area as Sarah Hartwell hints namely that some are fertile and some aren't. This probably has led to the disagreements.

Sometimes wild cat hybrids can have what is called hybrid vigour. When you crossbreed different species the resultant offspring can be larger than either of the parents. The tigon can be a large animal as shown in the photograph above. This sort of hybridisation would never occur in the wild because lions and tigers live in entirely different places and therefore never bump into each other. It is only when they are forced together in deliberate breeding in cages that they mate with each other.

It is unnatural and only done for financial profit and only viewed as a form of voyeurism from paying customers. It should be banned and probably will be banned in America because Carole Baskin is introducing new legislation which restricts ownership of big cats by Americans unless under certain specified conditions. The legislation would do away with the sort of exploitative place that I refer to and run by people such as Joe Exotic who you may remember is in prison serving a very long sentence (22 years) because he conspired to murder Carole Baskin. Joe asked Pres. Trump for a pardon! He did not get it.

They are archenemies but Carole Baskin is the good one. They are not the same sort of person which is why Baskin is annoyed at Netflix with their documentary called Tiger King which paints Joe Exotic and Carole Baskin as the same ilk. They certainly are not. Baskin saves the lives of tigers and other wild cat species from abusive private owners. She deserves a lot of recognition for what she does but she has enemies. Probably the enemies are people who like to exploit animals and don't see any reason to be decent and sensitive towards their welfare. There are a lot of people like that regrettably. 

There is one last point to make which is this. Through Darwin's theory of natural selection i.e. the survival of the fittest, animals become more specialised which enhances their prospects of survival in the places where they live. They are adapted to those environments. If you dilute their genes through hybridisation the resultant offspring is less specialised and therefore less likely to survive. Therefore this form of casual hybridisation goes against nature and natural selection as described by Darwin.

You cannot say that all cats hate water!

I have to confess that I have become a little bit frustrated and perhaps irritated by a large number of articles on the Internet which state with complete confidence that cats hate water. They are generalising about all cats. You can't generalise like that. You have to drill down and analyse the situation in far more detail.

The originan Van kittens swimming. Please click this link to read about the real Turkish Van

Firstly, you have to decide whether you are referring to cats walking outside in the rain and getting wet or whether you are describing bathing a cat or a cat falling into a bath or pond. When a cat, and I'm referring to a domestic cat in this instance, is submerged in water they will in general dislike it. You can pretty well bank on that. But it depends upon the individual cat as to how much they dislike it. Some may hate it and some may simply put up with it while others will love being in the bath.

Rain

However, you have to compare that situation with being out in the rain. We know that in the UK 99% of cats go outside whenever they like through a cat flap. They might go out in the rain. My cat actually goes out when it's raining sometimes. Clearly the rain does not perturb him. Or he is caught in a downpour and comes in soaking wet. It doesn't worry him particularly. Therefore this is, at least, one cat who does not hate water. He just doesn't mind getting wet.

So among the domestic, random bred cats you will find individual cats who might even like water and those who are ambivalent about it and those who dislike it or even hate it. There is a full spectrum of personalities which affects how they relate to getting wet.

Turkish Van

Then you have the cat breeds. There is quite a lot of talk about the Turkish Van swimming in water and liking it. This is a bit of a myth (see picture and link above). All the current Turkish Van cats in Turkey are random bred cats and they will behave just like random bred cats in America or the UK or anywhere else when it comes to getting wet. The person who started the Turkish Van breed was an English lady and she was driving home from Turkey with some cats and they went for a swim in a lake. This does not mean that all Turkish Van cats like to swim in ponds or lakes.

Maine Coon

I read somewhere that the Maine Coon cat likes to swim as well. This is a myth if you've heard it. In general, purebred cats will be no different to random bread cats in this respect.

The wildcat hybrids are much more likely to like or accept getting wet. Photo: in public domain.

Wild cat hybrids

You have to mention the wild cat hybrids. These cats such as the Savannah and Bengal have serval and Asiatic leopard cat DNA in them respectively to varying degrees depending on their filial. This affects their character and their relationship with water. Both the higher filial variants of these breeds are much more amenable to getting wet and even going into showers than the average random bread or purebred cat. 

This is because the serval and the Asiatic leopard cat live in wetter landscapes. The serval lives in and around watercourses and the Asiatic leopard cat lives in rainforests. They are habituated to wetter landscapes and climates. This has been brought forward in their DNA as a form of memory which has been embedded into the characteristics of these two wild cat hybrid domestic cats. That's why they accept or even like water.

Wild Cats

And then if you're talking about cats in general you must talk about the wild cat species. The tiger loves water and spends a lot of time in it. They are great swimmers and can swim in the open sea for miles. The jaguar in South America loves water and spends time in it as well. The small wild cat species, the fishing cat, spends most of its time in and around watercourses where it, yes, fishes. 

There are other the small cat species such as the flat-headed cat which also spends a lot of time on river banks near water. The Geoffroys' cat dives into water to hunt so once again a small wild cat looking much like the domestic cat likes water. All these species actively get into the water and therefore don't mind being wet. You can never say that "all cats hate water". Please don't do it! Rant over.

Wildcat facts in brief

The African wildcat should probably be referred to as the African-Asian wildcat because they are part of the same species. I don't want to confine myself to the African wildcat. This wildcat which is the size of a domestic cat is most distinguished for the fact that the Near Eastern subspecies a.k.a. North African wildcat is the wild ancestor of the domestic cat. They still look very similar. The African wildcat looks a bit like a diluted tabby cat. In fact there are many hybrids in Africa, the product of matings between purebred African wildcats and domestic cats. You could hardly tell the difference. The same hybridisation has taken place in Scotland where you might argue there are a few left who are genuine wildcats. Unfortunately the Scottish species of this small wildcat has almost been wiped out or perhaps has been wiped out by hybridisation with domestic and feral cats.

The domestication of the African wildcat took place perhaps about 10,000 years ago and it still takes place today in Africa. It is an extraordinary story. In terms of the way they look if I was more accurate I would say they are a little bit larger than domestic cats and a bit more leggy i.e. the legs are a bit longer and the cat is a bit thinner and rangier than the domestic cat. 

They are nocturnal rodent-hunters and they inhabit a very wide range, all the way across large parts of Africa, avoiding the Sahara mainly, through to the Middle East and over to China. They are also present in parts of Europe (European wildcat) and as mentioned in Scotland (possibly). They're said to be in Turkey and in India. The full list of countries is to large to set out here but also includes Uzbekistan, Turkmenistan, Tajikistan, Lebanon, Kazakhstan and Herzegovina.

Distribution of the wild cat 2020. IUCN Red List

If you want to know how the African wildcat behaves and lives you only have to look at the domestic cat. Our friendly, beautiful domestic cats inherited all those wonderful wild traits of the wildcat. The primary prey is small mammals such as mice and voles and sometimes birds, reptiles and insects. They mainly hunt on the ground but they climb trees beautifully and like vertical spaces. They drink very little water and our great survivors. We know their vocal repertoire because you just have to listen to your domestic cat to find out.

The population is decreasing which is unsurprising and their habitat type is said to be forest, savanna, scrubland, grassland and desert. You can see the general trend is towards a dry, arid habitat which is why the domestic cat is such a good non-drinker.

In Scotland, as mentioned, the Scottish wildcat is pretty well extinct and the threats to its existence across those large swathes of their distribution include hunting and trapping, as mentioned hybridisation by domestic cats, competition with feral cats for prey animals and human caused mortality through road kills. It is considered a pest in Scotland still which seems remarkable to me (is this true? Surely not bearing in mind the threat of extinction). Snaring and lamping in Scotland can sometimes kill them and habitat loss has led to declines in their population in Europe and in Russia in the 18th to mid-20th centuries.

What wild cats live in England?

The short answer is that no wild cats live in England. Just north of the border in Scotland there are some Scottish wild cats. They are part of the wildcat species. At one time it was thought there were about 400 of them. Now people believe there may not even be any genuine, purebred Scottish wildcats in Scotland. This is because they have crossbred with domestic cats to become hybrids.

This cat used to live in England but was extirpated and became extinct in England, as I recall, in 1835. This was because it was sport hunted to extinction. That's it. There is nothing more to say to answer the question in the title. It's a sad answer.

When is a Wildcat a Wild Cat?

We know that we have to protect and conserve endangered species and many of the wild cat species are endangered.  One of them is the Scottish wildcat. We also know that we have to deal with stray and feral cats. The way we deal with stray and feral cats is very often to euthanise them; in short, in many places they are killed because they are unwanted.

Scottish wildcat domestic difference 2

But in some places such as Scotland, the Scottish wildcat mates with stray and feral cats. This is interbreeding between a protected species and their domestic forms. In technical language the Scottish wildcat becomes an introgressed protected mammal. This means the genes from one species move into the gene pool of another species through interbreeding.

This results in hybrid Scottish wildcats.  The questions are:

  • How do you tell a hybrid Scottish wildcat from a purebred wild cat?  There are slight differences so it is possible to do this but it's tricky.
  • How do you deal with hybrid Scottish Wildcats?  On the one hand the cat is a feral cat to be disliked and on the other hand the cat is an endangered wild cat species albeit somewhat modified genetically. These are "in between cats".

You can see the difficulty facing conservationists and legislators.  People who create law often legislate about how to deal with stray and feral cats.  When they make these laws they have to define what a feral cat is in order to differentiate the feral cat from other species or types of cats.  Can they do it accurately bearing in mind what I have written above? How do conservationists deal with a melange of a species?

Many of the photographs that you see of Scottish Wildcats are almost certainly hybrids.  Many of the photographs that you see of African wildcats are also hybrids.  As I understand it, the North African wildcat is not yet endangered but when the time comes, as it surely will, to assess the African wildcat as endangered then it may be very difficult to know what to do about it because a lot of the cats will be hybrid domestic cats that look like African wildcats.
