When you’ve gotten a pet, it’s pure to be interested by it. What’s the title for its color? What’s that kind of marking known as? Why is its fur easy or wavy?
All these questions will be answered by figuring out the range your mouse belongs to. Fancy mice all belong to at least one species – Mus musculus, which we additionally know because the frequent home mouse. Nevertheless, they’ve been being bred as pets for almost 200 years, which suggests they now look fairly completely different to their wild cousins, with various physique and ear sizes. Not like rats, mice have tails and ears the identical color as their coat, however these coats can are available an enormous vary of colors. These have a number of completely different names relying on the place you reside. We’ve tried to provide the commonest ones beneath.

Agouti mice
Agouti is the pure wild color, outlined as being “a brown coloration fabricated from hairs banded (or ticked) in black, gray, brown and orange”. Agouti mice can are available a variety of shades relying on how a lot black there may be on the hairs, however they’re normally a heat chestnut. They’ve black eyes.
Like in rats, agouti may also kind a base for different colors and varieties, identifiable by having ticked hairs (some individuals name them ticked varieties for that reason). Widespread agouti-based varieties embody:
Blue agouti – slate blue color with black ticking. Eyes black.
Cinnamon – coppery brown fur. They’re similar to a traditional agouti mouse besides the ticking on hair is brown moderately than black. They’ve black eyes.
Argente – that is formally agouti modified by the gene for pink-eyes. That offers the darker elements of the hair tender orange tones, making the fur look yellowy with silver ticking. Some have a blueish undercoat, however some argentes don’t have this and look very orange. In search of the ticking helps inform whether or not your mouse is an argente or a purple.
Self mice
These are mice that don’t have ticking of their fur – their hairs are every a strong color. Widespread self varieties embody:
Black – goth mice! Black fur with black eyes. Mice don’t rust and fade the best way black rats do, and so keep extremely darkish.
Chocolate – brown fur, normally milk chocolate in color though the precise shade can differ. They’ve black eyes.
Blue – this selection known as blue however most individuals would name the color gray. The fur is a heat darkish slate color (not pale or chilly) and the mice have black eyes.
Lilac (Eur), Dove (US) – time for come complicated names! Technically this can be a chocolate mouse with the color modified by the gene for blue. The fur is a heat pale pinky-grey that goes browner as they age. The eyes are black.
Dove (Eur), Lilac (US) – complicated names half 2! These are genetically black mice whose color has been modified by the gene for pink eyes. That offers them fur of a greyish heat magnolia (or a heat magnolia gray).
White – white fur with black or purple eyes. The correct names for these varieties rely on the attention color, however white covers the necessities!
Tan mice
These mice can have any of the above self or agouti ‘prime’ colors, but in addition have a vivid orange tummy! The distinction is most evident on dark-coloured mice (e.g. black tan), however they will are available any color. In marked tan mice, the orange solely covers the non-white elements of the stomach. That is a type of colors that solely happens in mice and which some rat breeders are moderately jealous of.
Pointed mice
Think about a mouse sporting a magnolia (Siamese) or whiteish (Himalayan) onesie, however with holes reduce out on the nostril, arms, legs, ears, and bum permitting their ‘actual’ color can present by way of. That’s a pointed mouse, though most have a gradual color change moderately than a pointy line. The colored elements (factors) are clearest when the underlying color is a darkish self like black (seal pointed) or blue.
Patchwork colored mice
Brindle – this is similar precept as a brindle canine, and happens in any color. There are numerous completely different brindles around the globe and a few have sex-linked well being points, so it’s a good suggestion to analysis your native sorts earlier than adopting.
Splashed – these mice have colored blotches of two shades on a washed-out background fur color. Typically the blotches will be common with clear edges, generally the colors blur into the background extra. These mice may also have factors.
Merle/roan – an identical colouring to merle canine with two-tone splodgy patches over the physique. There’s a wide array on this selection from from large splodgy darkish patches (merle) to fur that’s principally ticked with silver (roan).
Marked mice
These mice have areas of white within the coat, and may happen on prime of any color selection. The markings will be so massive that they seem like white mice with colored patches. Widespread markings embody:
Dutch – white, with a colored blob round every ear and eye, and colored shorts.
Banded – a colored mouse with a white belt
Rump white – color on a lot of the physique, white from the hips down
Tricolour – a mouse with patches of at the very least three colors over the physique e.g. a splashed mouse with white markings. A tan mouse with white markings might or might not be known as tricolour relying on the place you reside.
Nevertheless, many marked mice don’t match right into a neat description. If particular patterns of white and color haven’t been chosen for in breeding, then the mice typically find yourself splodgy, with from only a few hairs of white, to only a few hairs of color, and something and every part in between.
Coat varieties
Pet mice don’t simply differ in color and markings – they will even have various kinds of fur.
Hairless
Hairless, “fuzzy” (US), Rex (Eur) mice – these mice are all on a sliding scale of lacking all or a few of their coat. Numerous genes trigger this; some won’t ever have hair, some will begin with hair after which lose it as they develop, some may have patches, some no physique hair however a couple of curly whiskers and so forth. There are many names for the differing appearances. The color of their pores and skin will rely on the genes they’ve for fur color with paler colors being pink and darker colors being gray.
Hairless varieties can have some well being considerations. Hairless mice are sometimes smaller than common as they’re consistently burning up energy to maintain heat with out furry insulation. The absence of eye lashes may also make them susceptible to eye infections. These with tightly curled fuzzy fur can undergo pores and skin irritation as it may be onerous for the mouse to groom mud and dust from between the hairs.
Astrex (Eur) and Rex/ Frizzie (US)
Astrex (Eur) and Rex/ Frizzie (US) mice have curly hair though they normally get much less curly as they age. They will expertise eye-infections in the identical means as hairless mice if they’ve decreased or very curly eye lashes.
Each hairless and curly coated mice have curled whiskers. Like many animals, mice use their whiskers as a sensory organ, serving to them assess their environment and discover their means round. Lacking or curly whiskers due to this fact elevate the danger of sensory impairment.
Satin
Satin mice have fur that could be very shiny or sparkly. The metallic impact is extra putting on some colors; generally you could solely have the ability to inform if a mouse is satin or not by their tummy hair. The impact is achieved by hairs that are hole, which adjustments how the sunshine bounces off the fur.
Longhair
Longhair mice, because the title implies, have longer hair. The coat can generally be barely sparser, and tends to be tender and floaty. Bucks normally have longer hair than does, however each sexes look shaggy as they age.
A number of of those coat sorts can occur on the similar time e.g. curly satin longhair isn’t unattainable. Though they don’t in themselves trigger well being issues, the extra uncommon encompasses a coat has, the tougher it may be to evaluate the situation of the fur (which pertains to common well being) and spot early warning indicators of issues.
Shorthair
Shorthair is the usual coat fancy mice have. It’s a easy shiny coat fabricated from brief straight hairs that lie flat to the physique when all is effectively. If the mouse is offended or unwell they will fluff the coat up so it stands on finish.
Commonplace coats shouldn’t be seen as boring – in addition to making it simpler for mice to precise themselves and house owners to identify well being issues, lots of the colors mice are available look extra distinct in a normal coat too.
Does selection have an effect on the well being of mice?
Many of the genes concerned in how a mouse appears to be like aren’t linked to both bodily or behavioural well being. Typically sure colors will be considered having a sure temperament or well being standing, however normally that’s coincidence as a result of breeding for temperament or well being within the line.
Nevertheless, there are some situations the place the genes that dictate look may also affect well being. We’ve already talked about these regarding coat kind above, however there are some points with sure colors too.
An important ones are purple (purple / ginger fur with black eyes) and fawn (purple / ginger fur with pink eyes). The coat of those mice is the color of probably the most reddish orange possible, and in addition to being large in color, they’re large in measurement. Overweight in truth. The gene that provides them their color additionally makes them super-efficient at digesting meals. To be wholesome, they want a rigorously managed and calorie restricted food regimen from a really younger age.
Marked mice with a number of white (together with black eyed whites, that are basically marked mice with a lot white there’s no color) can undergo megacolon, a deadly situation the place the intestines don’t transfer meals alongside correctly. It’s particularly frequent the place mice have been bred with no regard for well being. Affected mice must be humanely euthanised moderately than being left to undergo a gradual painful loss of life. As with different species, marked mice with out pigment on/close to the ears will be deaf.
Tailless (Manx) mice both don’t have any tail in any respect, or tail stubs. Some might even simply have shorter than common tails. Being utterly tailless will be very damaging to well being because the developmental abnormality that causes it could have an effect on their back-leg and gut perform. Nevertheless, even mice with brief tails can have issues. Mice use their tails to thermoregulate; they will increase and scale back blood vessel measurement of their tails to both improve the quantity of warmth loss (in the event that they’re too scorching) or minimise it (in the event that they’re too chilly). Additionally they use their tails like a fifth limb; the rationale mice are so nice at balancing and climbing is as a result of they use their tails each as an additional maintain for grip, and as counterweights. And one thing you may not know is that mice generally use their tails to speak with one another. So, having a stumpy or lacking tail dangers impairing their skill to control their physique temperature, their agility and their communication.
So which number of pet mice is greatest?
There’s no common reply to that query. We suggest avoiding varieties with linked well being issues, however as soon as welfare has been thought of, it comes right down to what appears to be like individuals want.
The place to seek out out extra?
This text has solely lined the commonest styles of mice discovered within the UK (the place Beri relies). There are such a lot of genes concerned within the look of mice that there are a whole bunch of doable appears to be like. Good web sites to learn extra, and for clear photograph examples are:
