> Prey tell then how do these phantom diseases you alluded to spread so rapidly into territory that has a decreased population of "small" predator species susseptable to these diseases?
Because the survivors need to cover much more territory to find a new couple, or quit the area searching for new refuges until to feel safe again, for example?.
Because marginal animals, looking for a place to settle, stop hearing territorial calls in the next hill and go there as fast as they can to reclaim the place for themselves?.
> Every plague in the known history of the Earth occurred when there was a plentiful amount of individuals crammed into a tiny space
Is not so simple as that. One animal can host the diseases that kill other kind of animals without being too much affected itself. The ecological concept of vector species deals with that stuff. Parasites are complex little buggers, often with complicated life cycles. If does not matter how dispersed or crammed if there is a mosquito that fills the gaps.
> within 24 months all 6 healthy deer had been killed by Mountain Lions but the three legged deer was still hobbling around the study area
Nice history, but, hemmm, this is a proof of... what exactly? bad sampling election? good luck?
Maybe we could conclude that the fastest, biggest and fittest adult deer are not so easy to capture by the scientists as the naive young ones? Do you understand that you can't trust statistics based in a such small number of animals?.
> Predators are opportunistic feeders
... therefore... if you have a safe frustrating coop they will choose the easier meal: Rodents, garbage, small fruits, passerines, bird feeders, carcasses, insects...
