Works out well. We get to advertise the C&C's and Petco is happy they don't have to provide anything.
Here is an excerpt from an email I got just today from the society I am a part of:
"MCRS partners with Petco to place adoptable rabbits in Petco stores. Thus, Petco houses adoptable rabbits instead of selling rabbits. It opens up spaces for adoptable rabbits and decreases the influx of new rabbits into the system that will eventually end up in shelters. Part of our agreement with Petco is that we will provide volunteers every day to exercise the rabbits for an hour a day, to make sure they have water and hay and to check them for obvious signs of health problems."
These are wonderful steps in the right direction.
