Since it is now winter, the little rodents come back into the house increases. Logically, when I buy a live trap, I do not want to hurt the animals actually. Although the event begins well, but a large proportion of mice particular house -and fire mice, the tail separated. So I'll need to dispose of this case now.
If the case was longer, this problem would certainly minimize or can completely resolve. This, however, higher costs would be incurred in the production (probably a reason for the brief case?)
