The brindle is a young adult whereas the PEW is an adult, but that still shows basic differences. Both are American.
As Willow said, exhibition/show mice have been bred selectively for a very long time with the specific goals of improving type to fit the standards as best as possible. Pet store or hobby mice may or may not have been bred as long (depending on individual lines), but without the same goals in mind.
Yeah, some of the sweetest, most laid-back mice I've ever met have been petstore mice, but there's just something about the large, racy body and the prominent, well-designed head/face of a showier mouse that really appeals to me, too. Plus, I like owning animals that I know have had years or decades of hard work put into them (whether that work is my own or others'). In a weird way, it's like owning a piece of living history.
Wow, that is a big mouse! Wish I could get my hands on something like that. Pet store mice are always small. I feed reptiles and when I go to the store and buy "the largest adult mice you can find" from the freezer, I come home and weigh them and they are sometimes as small as 12g. :shock: That to me is tiny for an adult! I usually consider a pet store mouse a fully grown adult when they reach 25-30g.
Had a weigh of a couple of mine and they are all around the 40 - 50g marker, one male that is trim in figure is 56g I must have big pet mice by the looks of it. I wonder if he has some big show mouse in his history somewhere. :think
I cant even imagine that mouse in the pic, must be as big as my hand easily.
Well all the pet store mice around here top out around 35g. I had one female who I was trying to breed (agouti). I had her for months and she never gave me any babies (turned out it was the male's fault). During that time she was around 30g. When she finally got pregnant after introducing her to a 2nd male, she weighed in at 35g during the pregnancy.
When I had pet mice (I'm in the UK) they were between about 22g (blue broken satin longhair doe, if anyone is interested) and 35g (black satin banded doe). I only weighed the first couple of mice I had though so I may well have had some bigger. The mouse in the photo was 15g and she was mine (bought from a pet shop injured, rehabilitated and then rehomed to a friend who had 2 does from my first ever litter). The cream doe in the photo was weighed for comparison and was 100g. I think this is exceptional though, I'm sure that my current creams don't weigh that much!
