I could get a barn cat, but I'd have to do it, like, weekly, what with coyotes and lotsa speeding gravel trucks 60 ft from my front door ;>
We do have 2 (previously more) semi feral cats hanging around, that our late neighbor used to feed. I don't think the cats do much for voles. There do seem to be more rabbits now that there are fewer feral cats, probably not a coincidence. Weasels prolly do a better job on the mice and voles but there's a limit to how much I want to encourage weasels, with the chickens.
So you don't see any difference in rodent damage in early vs late mulched beds, eh? I will have to think about that. It would be more convenient to mulch my perennials earlier... maybe I will do half the bed one way and half the other way and see what happens.
Thanks,
Pat
