Evidently contemporary baits aren't Warfarin based - that was the active ingredient I recall when growing up - it acts as a blood thinner, and rodents would haemorrhage internally whenever they bumped into something. A fairly unpleasant death. I'm not sure on the current commercial baits ingredients, but in any case, a good number of the rodents you're seeing in those photos will have been poisoned rather than trapped & drowned, so you definitely don't want your pets eating them. Having said that, a neighbour told me recently his dog had eaten some baits -- it was a bit slow for a few days, and 'shat green for a week', but seemed to weather it okay.
