I told my newfound rat friend that her rat must be a Siamese. I don’t think there are any around here, at least I haven’t seen any in the pet shops.

I had to go all the way to Milwaukee to get my rats. Last year, Petland had some Hairless rats, but I was afraid to get them because they seem so fragile! They seem to need much more care.

A Your friend’s rat does sound like a Siamese or Himalayan. I’m not surprised she found one. They were very popular in the pet shops for a while and just about every commercial breeder mixed them into their colony. The Siamese were first imported from England in 1983 (AFRMA was responsible for bringing them in). Unfortunately, a few

pet shops got hold of them and found they could sell them for a lot of money. All of a sudden everyone wanted one and huge numbers were produced with nasty, aggressive temperaments (many ended up attacking their owners) so they developed a reputation for being mean. That was the end of them as a fad, but many still crop up in pet shops. It’s not unusual to still find them with poor temperaments, so I’m happy to hear that your friend’s appears to be fine. Siamese rats are my “true love” among the rodents, and they are the reason I got involved with them in the first place.

Hairless rats are deceptive looking. They look fragile, but really they aren’t. Other than keeping them out of drafts (they do better housed in large aquariums) there isn’t much else special required for their care. I had one once, and she was a really nice pet. They really aren’t my cup of tea, but many people adore them. They do feel neat (kind of like a warm shammy). If you ever run across them again and they have nice temperaments, you might want to give them a try. Hairless mice are another story entirely. They are about as delicate as you can get, and they have all sorts of medical problems as well. Nichole Royer

A Hairless rat “Happy” owned by Gina Hendricks. She won Best Pet Rat at this show.

A Spotted Tan mouse (this is a Broken Merle with the Tan gene) from Virginia Pochmann. Note the orange by the back leg. This is where the top color “ran” onto the bottom and because of the Tan gene was changed from the Black, to the orange of the Tan.		A Black Broken Merle mouse owned and bred by Carissa Cosley. This has the appearance of being “tri-colored” with the patches of Roan, Black, and White.

A Tri-color mouse from 1980 owned by Linda Huscher. Note the large Black, Beige, and White patches.

True ‘Tri-Colored’ mice will have the different patches of color on their topsides similar to calico cats. Unfortunately, these mice are usually somatic mosaics, meaning this effect is only seen on that one animal and will not pass down in the genes so you cannot reproduce it.

If your mice produce more of the same of what they are, then you have one of the above possibilities rather than a true Tri-color.

There was a gene found in England that was reproducible and produced Tri-colored mice but had a waltzing gene linked to the tri-color part. The breeders there were not able to separate the two genes so gave up on continuing the lines. Karen Robbins

A Without knowing what the female carries, they only thing I can tell you is that the Down Under trait is dominant and originated in Australia, meaning you will get some marked like the dad in the litter. As far as what colors you will get, without knowing the background of the female colorwise and what they both carry in colors, is anybody’s guess. You can try contacting some of the clubs in Australia to help you in your breeding endeavors. Below is a table of Australian clubs you can contact to help you. Karen Robbins

A The answer to your question depends on what you mean by “two-colored offspring.”

The first thing to understand is that breeding two different colored mice together will not give you baby mice who have both those colors on them. That’s just not the way it works.

There are several very common and easy-to-find varieties which give you mice of more than one color. None of these varieties are things that you can “create” from scratch but they are all commonly found in pet stores.

Tan and Fox Mice: These mice have a colored top and either a bright orange underside (Tan mice) or a white underside (Fox mice). If you breed these mice to most other colors, you will get some babies who are Tan/Fox.

A Fawn Brindle mouse from 1984 owned by Karen Hauser.

Brindle mice: These mice are orange with black streaks all over their bodies. Ideally they have clear distinct stripes. Bred to any other color they will produce some youngsters who are brindled.

Black Broken Marked Std. owned by Karen Robbins, bred by Ann Quinn (Mile High Mice).

Spotted mice: These mice are white with colored spots on them. This gene is recessive, which means a mouse has to get the gene from each of its parents in order to be spotted. If you only had one spotted mouse you would need to breed its kids back to it in order to produce more spotted mice. A Spotted Tan mouse from 1980. Owned by Karen Hauser.

Spotted Tan Mice: This is the combination of spotting and Tan, and gives you a very pretty animal who has spots of one color on top, Tan spots on the bottom, and white. Some people think these are “tri-colored” mice but they are not. It’s simply the combination of the spotting gene and the Tan gene.

A Black Variegated mouse owned by Denise Deen.

Variegated Mice: These mice have solid colored spots on their heads and rumps, and a sprinkling of colored and white hair on their backs. If you breed them to any other color you will get some Variegated babies.

For more information on all these patterns and for pictures, I would suggest visiting AFRMA’s web site “Fancy Mice” pages (www.afrma.org/fancyrm.htm#fmice) or the Finnish Show and Pet Mice pages (www.hiiret.fi/eng/breeding/genetics/index.html). Nichole Royer

A A few years ago AFRMA shipped Tailless and Dumbo rats to Belgium. As far as I have heard, the Tailless line was doing well, and there are Dumbo here and there about Europe, so I think your best course of action would be to contact breeders and clubs in any of the local countries except Germany, as they frown on “Mutants” there. Try the International Rat and Mouse Directory or IRMD as there are many breeders all over the world listed. You can also get in contact with the Finnish Fancy Rat Society to find other breeders that may be interested in the same rats you are and would want to work with you to try and bring these into your country.

I do not know of any breeders of Dwarf rats on the west coast of the USA. There are breeders in the Central and Eastern states. As far as I know, Dwarf rats have shorter life spans and are much more prone to illness than other rats. Most of the breeders I know (all across the USA) do not breed them or recommend that they be bred.

Shipping overseas is expensive, 500 or more U.S. dollars just for the cost of shipping. The rats would cost 10–50 U.S. dollars each. The most expensive being the Tailless. Normally, when shipping like this, several of the AFRMA breeders will work together to be able to send all of the rats that the buyer wants in one shipment. Helen Pembrook
