Boys tend to smell more than females but they are solitary to where females thrive in groups, at least two or more. They can tend to bite more than rats do. but personally I believe it's the way they are bred that makes them aggressive. Like rats never hold them by their tails. When they get older they are known to get tumor and the like. Also they live about 1-2 years altough some can live longer. When the cage mates pass away they can consume eachother. In small close communities of mice this is rare but it can still happen. I feel like every mouse owner should know this as it can be quite disturbing to find unexpectedly. It's sad but it is sometimes their way of grieving in nature. Now about happy thoughts- What would you like to know about them?
My fav. have always been the angoras and curly haired mice. Angoras are long haired. in my experience my angoras and curly haired mice were alot sweeter than the standard short fur. But then again I use to breed them for show. so that could have been just good genetics. My males with an exception to a few were more reclusive in nature. The females seem to bond a bit faster. Males always fight when they grow up and it can become dangerous very fast. I've had alot of mice in the past and I was only able to have two males that I hand fed from the same litter be able to stay bonded through life.
