my vote...
I voted for mice. With a collection the size I have, I prefer to breed and raise mice and rats. Otherwise getting an order shipped waaay out here in ND is expensive! I end up paying as much for shipping as I do the frozen animals I buy! Yes mice stink, and YES they are a lot of work! I spend about the same amount of time working with my rodents as I do my snakes. So what are the pros? My mice don't have freezer burn, how can you beat fresh killed versus, you have no idea how long they've been frozen... Last time I looked, there is no date placed on the bags of frozen rodents! I've always got every size I need at any given time. And my personal choice, is I hate waiting to thaw out rodents. Heck I've even forgotten about a bag of fuzzies...TWICE... My wife discovered them after I had already left for work, and thankfully was kind enough to feed the young snakes waiting for their meals. With my own rodents on hand, pinks and fuzzies are fed live. Unless of course I've got a snake that prefers them dead. I LOVE my white mice. To me they are beautiful in their own right. I've tried to get colored strains, but haven't found any that prove out to be any good over the long run. I've hand brindles, but they get obese over time. I've had a friend's blue and white strain, but they throw runts, small litters, and have a cannibalistic streak. And others who just didn't produce. My white mice come from Petco. I was told they got mice in from Gourmet Rodent. They had the cheaper white mice, and what they called fancy mice. Well those fancy mice were mostly males and of larger size. My feeling is they were simply retired breeders! The white mice were small thus obviously young. I bought 1.3 and at the same time a group of brindles from another pet store, and a group of blue and whites from a friend. The White mice started slow, but when they started having babies, oh my did they ever! It's fairly common now to have 15 in a litter! They never get obese as they age. And I very rarely see cannibalism happen. So yes, it can be tough to find a good producing strain. But another point to make, is when breeding rodents. You should try to raise a couple generations before settling on a strain. My brindle line were great starting producers and did very well in the beginning. They were the majority for a while. I still have one female brindle in my colony. I keep crossing the brindle color to the white line. My hope is to breed out the obesity gene, but the obesity gene could be linked to the brindle gene. We'll see in time. I actually enjoy my rodent chores. So that's where I've got it better off than those who say, want to save money, but if you don't love rodents, it's NOT going to be worth it to you! I do it because to me it's more convenient, and I enjoy breeding and raising mice and rats as a part of my hobby. Why I didn't vote for rats, is because they do take up more space. In my opinion, don't rebreed immediately without trouble like my mice do. Plus since I only keep corns and similar sized snakes, I have to find an outlet for my retired breeder rats. Which I do, I sell to fellow snake keepers who have boas and pythons. Plus I've never had a problem with my mice biting. I think that's another aspect of my white line. The brindle line mice were nervous and jumpy. I called them popcorn mice when they got to the weaning stage! I can go in there now to my weaning box, pull out a white mouse, and it isn't going to be constantly trying to get away. They usually calm down with gentle handling, and will stay on your hand sniffing around. I always when setting up breeders, check for temperment problems. I also make sure they come from a large litter. Am now in the process of only taking breeders from litters of 15 or larger. And it's working! I can probably reduce the number of colonies in my bunch, I'm producing too many mice! My rats on the other hand, I have two lines currently. I got in some pretty blue, and blue and white rats. The trouble? the females are super aggressive! Will do anything they can to bite you, including through the wire tops! I HATE being bitten by them! Mice any day, but I usually never get nailed by a mouse! So am currently trying to weed out the super aggressive blues and hold back the not so ready to bite blues. Hopefully will breed out the aggression when I cross them into my Grizzly bloodline. Grizzly's as I call them, for the males, get HUGE. But all are laid back, even with new born litters. Never had a Grizzly line rat bite me.
