herbivore v carnivore?

[altezon]

so what makes it okay to kill some insects or rodents but not mammals, apart from making them extinct?
i like the cardboard as well. unless when you pull them off you leave their feet behind

I don't think anyone has made the distinction between insects and mammals (rodents are mammals too). The point is to respect any life enough not to take it carelessly or needlessly.

As a mouse struggles to free his feet from an adhesive tray his whole body gets stuck, but careful peeling won't even cost him any fur. A more expensive trap might be more humane, but these cost only a few cents apiece and are very effective.
