We're releasing this episode in time for International Rabbit Day – a celebration of our favourite floppy-eared lagomorphs. While rabbits do make wonderful companions, they are frequently released or dumped in the wild – and with an exceptionally quick gestation period, that can lead to a lot of domestic rabbits in the wild, really fast.

Mustachioed dog-nappers chasing animated pooches around the city may be what's in some of our heads when it comes to animal control, but the important front-line officers in our communities go well beyond that trope.

The search for home is something most people can relate to, at some point in their lives. Regardless of circumstance, that need for the place that is yours, surrounded by the people you love, and the sense of wellness that comes with it, is a universal desire. And it's not just for humans. Animals bred and kept as livestock – or farmed animals – have similar feelings and needs. And one incredible...
