Special (very long, thorough – don’t make this your first Urban Wildlife Podcast episode) Episode: Billy, Tony, and biologist Clint Springer dive into the outdoor cat literature. This is a companion to our Cat Wars episode. Finally we sat down and went through the literature cited by Alley Cat Allies as well as the literature Alley Cat Allies doesn’t tell you about: what is the impact of outdoor cats on wildlife, and what have scientists learned about how to control un-owned cats? We actually changed our perspectives a little bit: TNR is ineffective, but without controlling cat dumping and cat feeding, it is really hard to control stray and feral cats.
Here are the sources we discussed in the order we discussed them.
