Ah u must be American. most of yr urban wildlife- aka birds, small mammals, lizards etc already dead due to pussycats.
Here in Australia, cats are considered feral animals altho they are still widespread as pets. They kill native birds, small possums, etc at a rate of about 100/year. Most rodent poisons have a secondary kill in them which takes out owls and other predators who eat the poisoned rodent.
Try the cement flour method and leave access to water right outside the building w the infestation. Might just do the trick without harm to native wildlife.
