    Yeah, I know. They are a pain in the butt. But they pay the bills to keep my server running. Just a fact of life, I am afraid.

    Want to get rid of them? Simple. Just become a Contributor level member or above and they will be gone. -> Please click HERE."

    Is that too much for me to ask of you to keep this site running? Well, sorry about that. I too wish I could get everything for free. But alas.....

    Google Adsense ad revenue for December, 2025 was just $30 over the cost of the lease for the server running this site. So, in effect, the money providing the incentive for me to continue running this site is coming SOLELY from the paid memberships and sponsorships here. Which honestly ain't much....

KEEPING AND BREEDING FEEDER MICE FOR REPTILES

At one point in time or another every owner of a carnivorous reptile will decide that they want to try their hand at keeping mice to be used as food items. While this is a very useful means of solving the problem of a constant food supply it is not for everyone. Mice require just as much work to raise as do the reptiles themselves. The mice must also be fed and this cost should be figured into the factor when determining the cost of raising your own mice or purchasing them.

The first thing to note when raising and breeding feeder mice is that they should be treated just as good as the reptiles that they are intended to be food for. This will help to prevent the spread of disease and parasites to your reptile and it is just plain cruel to the prey animal. This is also just another reason for pre-killing the mice prior to feeding, it reduces the risk of harm to the reptile and is more humane for the prey animal.

Housing may be achieved by keeping the mice in 10 gallon glass aquarium. Inexpensive lab cages designed specifically for mice may also be purchased and are available from most reptile supply houses and specialty mail order firms. Pine shavings may be used for substrate or torn newspaper may be used. The newspaper is less expensive, but is messy and requires more frequent cleaning. Cedar shavings should NEVER be used as a substrate as it is known to be harmful to mice. A <a style='text-decoration: none; border-bottom: 3px double;' href="http://www.serverlogic3.com/lm/rtl3.asp?si=22&k=water%20bottle" onmouseover="window.status='water bottle'; return true;" onmouseout="window.status=''; return true;">water bottle</a> should be provided and is best secured on the inside of the enclosure with velcro strips.

Mice should be fed a varied diet including hamster/gerbil food, lab blocks and some <a style='text-decoration: none; border-bottom: 3px double;' href="http://www.serverlogic3.com/lm/rtl3.asp?si=22&k=dog%20food" onmouseover="window.status='dog food'; return true;" onmouseout="window.status=''; return true;">dog food</a>. All of this can be purchased at most <a style='text-decoration: none; border-bottom: 3px double;' href="http://www.serverlogic3.com/lm/rtl3.asp?si=22&k=grocery%20stores" onmouseover="window.status='grocery stores'; return true;" onmouseout="window.status=''; return true;">grocery stores</a> and <a style='text-decoration: none; border-bottom: 3px double;' href="http://www.serverlogic3.com/lm/rtl3.asp?si=22&k=pet%20stores" onmouseover="window.status='pet stores'; return true;" onmouseout="window.status=''; return true;">pet stores</a>. A constant supply of food should be available at all times.

The enclosure should house about 4 females to 1 male. Once the male has copulated with the female, she should be removed from the group. It will be about 21 days until the female gives birth to a litter of 5-15 pinkies. Average litter size being about 15 pinkies with some females having as many as 20 in a litter depending upon their overall age and general health. About 21 days later the young should be weaned and eating on their own. The female may then be returned to the group enclosure. At 45 days out the young should have matured into adults.

Cage Cleaning should be done 1-2 times a week. Dispose of the substrate and wash the tanks with soap and a very mild bleach and water solution. It is important to ensure that the tank is very well rinsed and dried thoroughly before replacing the wood chips and mice back into the enclosure. Make sure that the enclosure lid is secure at all times. Loose mice are not only difficult to catch, but often are not and may begin to breed in your home.

While any color mice will do just fine, it is the white lab mice that seem to be the hardiest and tend to be more prolific breeders. The average breeder will continue to breed for about 1 year. The female breeders should be replaced about every year and the male should be replaced about every year and a half.

Temperature is very important and the mice should be kept in a room where the temperature is about 65 to 70 degrees F. Temperatures above 70 degrees F. tend to cause their production to slow down, and if kept at temperatures above 70 degrees F for prolonged periods of time they will eventually die.

Being patient is the key and you may have to experiment a little with the basic concept in order to find a method that is both effective and convenient for you.

I don't agree w/the above statement. I use the single, shoe-box sized mouse breeder units that hold food and water bottle on top. I have 4 females and 1 male in each one. I do NOT remove pregnant females. In my experience, if you remove an adult mouse, most of the time you can't put her back. They will kill her. You usually can't add any new mice if one dies either or they will kill him/her. This is in most cases, I'm sure there are exceptions to this but I've rarely seen adult mice accept a new one.

In my experience it's best to replace the whole bunch at around 8 months of age. Especially when the male is fat and looks like a pregnant female, he's past his prime and will not be a good breeder.

A good way to keep the smell down is to use imitation vanilla 8 drops per 12 oz bottle and baking soda in the shavings. It really knocks down the stink.
 
frozen/pre-kill

i really got sick of raising and buying live mice so i tried ordering online from a site called rodentpro. Usually a live mouse costs anywhere from 90c to $1.50 which gets very expensive especially of you are feeding monitors and snakes with rodent only diets. anyway i bought 200 hoppers and 100 large pinkies and instead of paying $450 which is what they would have eventually cost at my local petshop they cost me $90 including shipping. i highly recommend this company because from all my shopping around they have the best prices and are a high quality company. also frozen is always the healthiest way to go if your herp will take it. i also believe that whenever any one makes a herp purchase they should make sure it will eat frozen thawed rodents or birds. oh, and a good way to thaw is to put frozen mice on a plastic bag(no holes) and put it in a glass jar FULL of very hot water with the top part of the bag hanging out and screw the lid on the top. also a good way to warm them back up is to put them under a basking light for a couple minutes. just a few things ive learned that i wanted to share. peace
 
I agree with Karen 100%. I never remove the female from the tank either, learned that one the hard way. The other mice almost inevitably will kill her when you try to re-introduce her.
