Yes!
I caught a deer mouse in my apartment and opting against letting it die slowly and painfully on a mouse sticky bait; I carefully found a way to pull it off and placed it in a 2.5 gallon aquarium. (* Catchmaster Brand mouse sticky pads are very weak and it is easy to pull the mouse off the trap vs. other brands where the mouse will be permanently stuck! Just make sure you wear vinyl gloves to protect your hands and fingers from a potential bite (and vinyl does not stick as permanently to the glue. Also note that you will have to use "gentle force" while pulling your little critter off of the trap. PLEASE BE CAREFUL NOT TO HURT IT!).
In any case, I fed it extremely well for a couple of days and he always took note to run and hide under the protective shelter that I had created for him--Okay Yes, I was plotting to keep it if I caught it! I even went to the pet store and brought the fancy mouse mix so that it would never want to seek the wild again. Yeah right! While attempting to clean his cage my little friend Sir Pennington Copperbottom jumped out and scurried away with the speed of greased lightning! My husband said it was the name I gave him. I was broken hearted plus "broken wallet-ed" because of all the high-grade fancy stuff I had just purchased (mouse dust bath included). SOOO instead of letting all that good stuff goes to waste I went to the pet store and purchased a fancy mouse that kind of reminded me of Sir CP. It was a female. Her name is Lady Jane Gray :)
I guess you're wondering where this is going... well a day after Lady JG was settled in her cage, who got caught on the same sticky pad...? Well, I think it was Sir PC because he was able to do the same full back flips that the original Sir CP was doing previously. I have had mice, hamsters, gerbils, and even a rat so I understood that as long at it wasn't two males I should be fine with them getting along. I was less concerned with breeding because for the life of me I was certain that two different breeds of mice would not mate. Besides Lady JG was more than twice the size of Sir CP. In my mind there was no way he could climb that mountain! Well he did... and quickly! Lady JG gave birth to four babies and they seemed like such a loving and protective pair. They would groom each other and always slept nested together and never fought. Sir CP even started to appear to get used to me getting close to the aquarium and would not runa away as quickly.
Needless to say while removing soiled bedding and adding a fresh batch to one corner of the cage, Sir CP once again jumped right out of the aquarium and ran away. Funny thing was... he hesitated for a while before taking shelter behind all the wires stemming from our computer/media center then running to freedom. Hmmm....
Sorry I wrote so much... I'm a writer. Force of habit :)
fancy mice
It is possible, but it is not safe because it can result in deformities.
Deer mice are not endangered. Listed as "Least Concern".
If it is a pinky that was breed for snake food than no, pinkys are breed just for food, a pet fancy mouse is the way to go. If bought from a private breeder they can be more friendly and will have much better health.
No. Deer are herbivores - they don't eat animals. Herbivores are plant eaters.
Mice and deer do not have hobbies
yes
Yes, deer mice have territory. Deer mice have about 242 square meters to 3000 square meters of territory. Hope this helps :)
The best type of mice is the Fancy female mice, you must get 2 for healthy pets they are nicer than males and don't smell as bad as the fancy male mice.
This is a misnomer. Fancy mice are the exact same as feeder mice, they are usually just more colourful and sometimes tamer/handled more often as they are intended as pets.
Deer mice eat seeds and fruit. They eat insects. They also nibble on dead animals.
If by Fancy mice you mean Show mice, & common you mean pet/lab/snake food mice, then yes, they do mix. They're all basically the same animal, just different variations.
