Since when is 60-65 too cold? My garage runs into the upper 40's on the coldest nights and my mice are all doing just dandy. And like someone else said, they do tend to breed better when its colder out. Too warm of a temp has more of an adverse effect on their reproductive patterns, at least here in my home.
Personally I'm pretty shocked at some of the replies on this thread.
Have I ever taken my sick mice to the vet? No. They're not worth $60 to find out that its sneezing is an RI. If its sick, I euthanize it, feed it off, and raise up a replacement.
Maybe if I were raising show mice and could never bear the thought of one of the little buggers dying...then maybe it'd be worth it to me.
Did I take the rat that's been bitten on the base of the ear that now has a perma-lean because of a balance issue? No. She's still productive and does just fine even if she does walk like she's on a rocking boat.
Sure its a living creature, and I dote on my feeder rodents more than some people...but in the end, its still just a mouse. Call me cruel, I could care less.
I'm not raising show mice that could fetch $30 each (or $5000 in Gintha's inflated universe). Maybe if I were, I'd be more apt for veterinary care. I raise my mice for snake food. So if it ultimately meets its end sooner than I had planned, no skin off my teeth.
How many of you saying such things set mouse traps when mice eat your blessed Oreos? All of this venom over a mouse isn't productive. No one chews a new ass for newbies with 3 snakes in a 10gal. Instead they get coddled along anymore.
And what annoys me, she hasn't even said what she's housing them in, what the substrate is, what the diet is, etc. Yet everyone's prematurely running off with the train and jumping on her case because she's "improperly" caring for them.
Although I do agree with Wilder, if the mice are being sold for only $1, they're more than likely feeder bin rodents. And nothing ever good comes from the feeder bins. They're over-crowded, diseased, and most are well past their prime. That's why they're there. Pet mice here in healthy shape cost $2-$5 depending on the store.
Sugar water catches a lot more flies than vingear. And for some reason I see this as aligning along the lines of those who don't raise their own feeder rodents and those that do. It's a sad reality out there sometimes.
Think about where your eggs come from...think about 8 hens cramped into a 12"x24" cage so tightly they can't even open their wings or stand up..day after day spitting out an egg. Most die after 6 months of age in such conditions. But every dozen "store eggs" you buy you support such inhumane practices. Just something to think about as you think she's cruel and heartless over a mouse.
