Sarah's African river litter

H3gzi's Safari, owned by Sarah, and Babbett's Mimer, owned by Matmor, were mated 2008-12-07. 2008-12-30 Safari gave birth to 11 healthy pups that all grew well. 7 were boys, 4 girls. There were no stillborns in the litter. Eight out of eleven rats were still alive at 24 months. At 30 months two were among the living. The last one to go was euthanised at 35 months.

In collaboration with Sarah the information on the litter is placed here.

This page would not be possible without the support of the customers who have sent us updates. Thank you, all of you!

The beginning

Advertisment at NTF's forum 2008.11.18

We would like to see Safari and Mimer get their holiday fling in late in December - and now we wonder who will be interested in the kittens. Safari, born 27/4 2008 among H3gZi's Litter, are agouti berkshire rex carrying dumbo (AaHhDuduRere). She is a lively girl filled with curiosity. Introducing her to the cagemates no problem at all. She has never been ill. Owner: Sedra (NTF nick) You can read more about Safari at (Norwegian only)

Babbett's Mimer, born 16/8 2007, is a ruby eyed mink berkshire (probably aaGgHhmmRrDu-) with a 50% chance of carrying dumbo. Mimer is a calm snugglebear with an excellent temper. He has been through several introductions as an adult, both with babyrats and adult males, and always behaved like a perfect gentleman. He has never been ill. Owner: Matmor

We expect agouti and black self, berkshires, hooded, rex and standard, with a possiblity for dumbo. Other colors are possible as both Safari and Mimer may be carrying several colour modifying genes. Safari's pedigree can be viewd at Matmor's home page under Mimer, Mimer's pedigree is available at Klick the link under Mimer on the page Small creatures, great personalities.

NB! Safari's and Mimer's pedigrees have been removed as it is not neccesary to maintain them when the information is included in the pedigree for the Sarah's African rivers litter

Safari 14 days pregnant


Sarah brought Safari and a companion to Matmor 2008.12.06. Safari came into heat 2008.12.07 and spent the night with Mimer. Frequent copulations were observert. The wax plug, however, was not found next morning. Because Safari's weight gain was slow and somewhat uneven, Safari stayed with Matmor until we felt confident she was pregnant. Safari was noticably more rotund by day 12. She started to build a nest at approximately day 14 and lost the hairs around her nipples at day 16. She was returned to Sarah 2008.12.25 and placed in a birthing cage on the 2008.12.27. The pups were born in the afternoon of 2008.12.30.

Safari's weight before mating was 351g. She started by loosing 3 g at day 1 - the two of them must have had one busy night. After a week of uneven weight gain she had put on 26,5g, but the she lost 7,5 g again. The day after her weight was even one g less! Eventually I discovered that weighing her each morning before breakfast gave more even results. From day 10 and onward she gained weight every day, but the increase varied between 1 and 17,5 g. At day 21 she had gained 107 g. After that she was not inclined to be weighed, so the exact weight gain before birth at day 23 is not known.

2) small "bellyspot" on her side, could be a self genotype 2009-02-06.
All the pups are carrying mink (Mm). There is a 50% chance that each carries ruby eye (Rr), siamese (Cch) and (English) blue (Dd).
According to the pedigree they have slimmer chances of carrying mock mink (Momo), (European) Husky (-/hRo?) and Russian blue (Rbrb), and even less likely chocolate (Bb) og pink eye (Pp). Since one of the pups turned out to be a dumbo the top eared siblings have a 66,6% chance of carrying dumbo.

Weight development

2009-01-01 (dag 2) 1 pup weighed 7g, 2 pups weighed 8g and the rest 9 g.

Benue "Mimmi" weighed ca. 95-100g day 35 according to the owner.

Belly markings

None of the pups inherited Safaris fine, symmetrical "bikini triangle". Some, however, got dark belly spots from daddy Mimers. I am inclined to believe that the dark spots are a dominant trait, as I have not heard of dark belly spots in Safari's family. Possibly they are mainly expressed in the males? I refer to the name "pungflekker" (testicle spots), which is well known in Sweeden. If anybody knowe how these dark belly spots are inherited (not downunder) I am interested... However inherited, these belly markings, and the white ones, develope over time. Just look at the bellies of Bahr el Zaraf and Limpopo as babies and as adults!
Mimer's belly (more dark spots higher up on his chest)
Baby Bahr: dark belly spot and testicle spots
Adult Bahr
Kasai: squiggly European Berkshire
with two small black spots
Jubba: squiggly European Berkshire,
no black spots
Olifants: two "mammary spots" and a testicle spot
Victoria: assymetric European Berkshire
no dark spots
Baby Limpopo: assymetric European Berkshire
Adult Limpopo: assymetric European Berkshire
Benue "Mimmi": fairly good european berkshire
Afrik and Mania are Self so dark belly spots will not show if inherited.
