I haven't yet seen these mentioned on this site, so if your not sure what they are, multi-mammate mice are like the missing link between mice and rats, they are much larger than a mouse yet smaller than a rat, they carry both characteristics of mice and rats, they aren't as finicky or hyperactive as mice and live each day as it comes, they can be very loving and playful if handled from young, and love to laze around like rats. They are also extremely social animals, and can be kept in large colonies, but don't do well at all on their own, they become depressed and lonely which can result in death. Some people even raise a young multi with a mouse, rat or gerbil and they've been known to live their life out with a different species cagemate with no problems at all, i only have 1 multi that lives in a different species colony, due to her mother rejecting her, she was half the size of a normal pinky and i knew she would die, so i introduced her to a mouse colony who also had newly born pinkies, and they took her in with no problems, she is a beautiful adult multi now and still lives with the mice, shes still slightly smaller than average, but very healthy all the same
They get their name because their average litter is almost double that of a mouse or rat, they have more nipples than your average rodent and for that reason are used in laboratories and for livefood breeding usually.
The only thing you must consider when taking on a multi is that they are escape artists and great chewers, you cannot keep them in a plastic tank as they will chew out and they even chew through some meshes, so a metal cage or glass tank is required with a secure lid! you may notice in my pics some are in plastic tanks, but they are going to be changed next week for the very reason they now have holes in the bottom which i have had to patch with wire mesh
anyway enough babbling, here they are!
