The Shaw's Jird (Meriones shawi) is about the same size as a rat and looks like a giant version of the Mongolian Gerbil. Indeed, the two species are closely related. They both belong to the same branch of the gerbil family, The Jirds. The Mongolian Gerbil is in fact not a true gerbil at all but a jird. Its proper name is the Clawed Jird (Meriones unguiculatus).

The Shaw's Jird originates from the arid areas of North Africa and the Middle East. It has been used extensively in research laboratories but has only been kept as a pet relatively recently. Up to about 10 years ago, a similar species, the Libyan Jird, was kept as a pet but the Shaw's Jird has been found to be friendlier and to make the better pet.

Shaw's Jirds make wonderful pets. They have the same innate friendliness and natural curiosity as their Mongolian cousins. They rarely bite and enjoy being handled. Being that much bigger, they are easier to cuddle. They are also extremely intelligent. I let mine out for a run around my flat and have no trouble recapturing them. I just call them and they come to me and let me pick them up. I have also trained them to go to the toilet on a piece of newspaper placed on the floor for this purpose. The only problem with giving them the freedom of the room is that being rodents they will gnaw at everything. Shaw's Jird have bigger teeth than Mongolian Gerbils and are able to cause more damage. It is important to make sure that all electric cables are beyond their reach. In my case, the telephone was a perennial problem. After being cut off the phone three times by probing gnashers, I had to get BT to come and move the plug so it was four feet up the wall. Shaw's Jird seem particularly partial to ripping up wallpaper and pulling chunks out of the carpet. Pet jirds should be kept as a pair in the case of males or singly in the case of females. (See the section on breeding below for an explanation of this).

The Shaw's housing requirements are similar to the Mongolian's. I find that a 30" aquarium provides adequate accommodation for a pair. As with my Mongolian Gerbils, I make permanent tunnels at the bottom of the tanks with clay pipes, large jars and other ceramic containers, and I cover this with a deep layer of wood chips. Whilst female Shaw's invariably make use of the pipes for their sleeping quarters, males often choose to remain on the surface whilst they sleep. This may be because the males prefer to sleep stretched out on their backs with all four paws in the air!. This is just one of the differences between male and female which contributes to problems with compatibility. (See the section on Breeding below for more on this).


Like Mongolian Gerbils, the basic diet of the Shaw's Jird is a mixture of seeds and grains. However, they are more omnivorous and relish variety. Unlike Mongolians they enjoy all types of fruit and vegetables. They also need a small amount of meat. Some breeders give them tinned cat food. I give mine mealworms twice a week as I find this less messy.

If you just want to keep Shaw's Jird as pets and do not wish to breed from them, then you should choose either two males or a SINGLE female. A pair of males will live happily together and as with Mongolian Gerbils appear to become very attached to their partners. Females, on the other hand, are much more aggressive towards other jirds. (They are fine with people). If they have been introduced at an early age, two females may live together amicably for a while but they are likely to start to fight as they get older. Unfortunately, the same is true of a mixed sex pair and this makes breeding Shaw's Jird very difficult. Female Shaw's are dominant. They are very territorial and will monopolise the bed, bedding and food. No matter how much food and bedding is put into the cage, the female will take it all mouthful by mouthful and store it in her bedroom. Should the male be foolish enough to try and enter this sacred domain or to impede the female in any way, the female will grab his tail in her mouth and pull hard. If she grabs the tip of the tail, then she may pull it off. More likely she will inflict a nasty bite. As the harassment continues, both male and female will begin to show signs of stress. Their noses may bleed and a blood-coloured discharge may come from their eyes. Both will develop scabs from bites on their tails and feet. As soon as the lid is taken off the cage, the male may try to run away. Unlike incompatible Mongolian Gerbils, I have never known Shaw's Jird to engage in mortal combat. Nevertheless, there usually comes a point when for the health of both they have to be separated. How then is it possible to breed from Shaw's Jird? Most of the ones I have bred have been from young females. Females mature early and if they are paired with an older male are likely to mate when they are around ten weeks old. One or possibly two litters may be successfully raised before the pair have to be separated. With older females living alone, it is a case of putting the male in her cage for an hour or so when she is on heat. This is quite easy to detect. If the male is held close to the female's cage so the pair can smell one another, the female will wag her tail vigorously if she is on heat. If she is not on heat, then she will squeak loudly and attempt to attack the male. The gestation period for Shaw's Jird would appear to be similar to Mongolian Gerbils, 24-26 days. However, young Shaw's develop faster. By the time they are 16 days old their eyes are wide open, they are fully mobile and they are eating solid food voraciously (unlike Mongolians who are only taking their first tentative nibbles at this stage). From this time on they grow incredibly quickly. However, their mother continues to keep a watchful eye on them and it is not uncommon to see her struggling to pick them up in her mouth and return them to the nest until they are about four weeks old. Like Mongolians, Female Shaw's come on heat a few hours after giving birth. If a successful mating takes place, then a new litter will be born when the previous one is only just over three weeks old. Though this is not desirable, Mongolian Gerbils seem to be able to cope with this and successfully rear the new litter. Shaw's Jird, don't and any litter born as a result of a breed back in this way is likely to be neglected and die.

Young Shaw's Jirds


Information about Shaw's Jird is extremely difficult to find. I have only come across the odd paragraph about them in books on gerbils and other rodents. However, if you are seriously thinking about acquiring a breeding pair then you might like to take note of the following:

"The world's greatest mammalian lover is Shaw's Jird of North Africa, which is frequently used as an experimental laboratory animal. One 60g male was observed to mate 224 times in 2 hours!" (Wood, G L The Guinness book of animal facts and feats 3rd edition Guinness Superlatives. 1982)


There is a good site devoted to Shaw's Jirds.



Some Notes on Shaw's Jirds

By Julian Barker

First Appeared in the NGS Journal, March 2001


After the Mongolian Gerbil (Meriones unguiculatus,) the species of gerbil normally kept as a pet, Shaw's Jird (M. shawi) is easily the next most common species of gerbil seen in British pet shops - so common is this gerbil that in Britain the word 'jird' is synonymous with Shaw's Jird, despite the increasing popularity of other jirds. Despite its popularity as a pet, I have found very little written about how these gerbils live in the wild.

The Shaw's Jird is a large gerbil. Males can easily grow to 350mm (14 inches) or more in length. The tail is usually half the overall length. Shaw's Jirds look very much like a large Mongolian Gerbil. The main differences, other than size, are the usually darker colouring, (although lighter coloured Shaw's Jirds are known,) a less prominent tuft at the tip of the tail, and larger ears which are much less hairy than those of Mongolian Gerbils.

There are at least two sub-species of Shaw's Jird, and Shaw's Jirds are similar enough to two other North African species, the Libyan Jird (M libycus) and Sundervall's Jird (M. crassus) to have caused decades of confusion amongst taxonomists. For many years Shaw's Jirds were thought to be no more than a sub-species of the Libyan Jird, but genetic an breeding studies have shown that they are different, if closely related species. The Shaw's Jirds we have in the UK share characteristics that normally differ between Shaw's Jirds and Libyan Jirds. This may indicate that they are in fact hybrids.

Shaw's Jirds come from the coastal regions of North Africa. They are known from Morocco, Algeria, Libya and Egypt. They prefer either sandy areas near to date palms or clay soils near areas of cultivated barley. They dig extensive burrow systems with many entrances. They are mainly nocturnal, although occasionally seen on the surface during the day. They are know to be predated upon by owls.

Shaw's Jirds do no appear to have a specific breeding season even in the wild. Sexually active males have been observed in March, July and November. Depending on the climate their numbers can suddenly increase and can become a menace to agriculture.

In captivity it is easy to keep Shaw's Jirds. They are easy to handle and make excellent pets. Apart from needing more space, they can be kept more or less the same way as Mongolian Gerbils. Shaw's Jirds are less communal than Mongolian Gerbils, so they may sometimes be less willing to share a tank with other jirds. As shown in the picture illustrating this article, many domesticated animals have white spots on the head, and sometimes on the tip of the tail.

It has been noted that Shaw's Jirds kept in mainland Europe are different to those that have been present in the UK since at least the 1980's. British animals tend to be larger, have thicker tails, and broader facial features. The two types do interbreed and it may be that UK Shaw's Jirds have undergone hybridization with Libyan Jirds, or it may be that UK Shaw's jirds are derived from a different region from the European variety, and may therefore be derived from a different sub-species.

Are all Shaw's Jirds the same?

There seems to be a lot of differences between the animals that are called Shaw's Jirds in the UK. It may be that in fact these jirds are the result of breeding together various sub-species of Shaw's Jird, or even the result of hybridisation with Libyan Jirds (Meriones libycus).

There appears to be the following visible features:

  Type Size Colour Face Ears Tail
[Picture] Southern Larger Darker Greyer Long Dark Dark
[Picture] Libyan Hybrid? Larger Lighter Oranger Slightly Longish Lighter Dark Tip Only
[Picture] Dutch Smaller Darker Greyer Shorter - Rounded Snout Dark Dark
[Picture] German Smaller Darker Greyer Short - Pointed Dark Dark

NB, the names are only my shorthand based on either their origin or the place where I have seen them. So for example, it doesn't mean that all Jirds in Southern England are "Southern Type" or that all animals in Germany are the "German Type". Also, please note that the colours in the pictures is very dependant on the lighting conditions under which they were taken.

Not only do Shaw's Jirds vary in appearance, they also vary in temperament.

German and Dutch jirds (that I have seen in the UK) seem to be much more timid and more difficult to handle than the other types. You can see this by the hunched appearance of these two types in the photos above.

There are several known subspecies of Meriones shawi and it is known that even in the same sub-species, there can be significant differences in colouring. This is true for almost all mammalian species. See -  DESERT COLOURATION IN RODENTS: David L Harrision, Chapter XIII, pages 269-276 of RODENTS IN DESERT ENVIRONMENTS, Prakash, L and Gosh, P.K. (volume editors), Dr W. Junk b.v. Publishers, The Hague., 1975, 90 6193 080 4

This hand coloured print by J Smith and published in Proceedings of the Zoological Society in 1884 shows an animal looking very like the German/Dutch type of jird, rather then the type more common in the UK.






Coat Colour Mutations

For many years now Shaw's Jirds in the UK have often exhibited a small white spot on the forehead. More recently, a spot on the neck and a white tip to the tail have started to appear in some Jirds.

In addition, the colour of Shaw's Jirds varies a lot in intensity. They can vary from orange to very dark with a lot of grey. But all these animals are clearly Agouti. This variation is likely to be due to modifying genes and not a major mutation.
