Although it is possible that you might poison both the mouse and a predator, it always seems to me that this is unlikely, since most poisons are fast acting and painful for the mouse so in all likelihood it will die in its burrow. Predators, in general, do not feed on animals that they did not kill, although there are certain exceptions to this, but this will exclude most pets.
I wouldn't put down poison where it could be eaten by pets by mistake, but I would use it inside a space that was known to be pet free or via a bait box (like these) that was pet safe.
Personally I prefer to use snap traps, however these aren't helpful if you aren't there to dispose of the bodies and reset them (so glue traps like these are out on the same basis). Most of the electronic stuff looks like gimmicky trash with mixed results at best (and all are shunned completely by the professional), so there seems little alternative in any case. Anybody that has had rodent damage knows that doing nothing isn't an option, especially if there is a ready food source nearby.
