My backyard is clean and almost empty (no spaces to hide). My neighbor has 2 cats. My question, what do you think did happen? to me is like someone (not human probably) throw them all or kill them all. But how and why the babies were there too? I was thinking maybe my neighbor cats did that (not complaining) but I want to know what could happen and if you there there are more? it scares me really.

How the rats died is not important at this time. The fact they are
dead is what matters. The neighbor and I went on a rat killing event
last year. So far we have been lucky. Pellet rifles, boots, shovels
and seeing them drown was worth the effort.
