Hi,
I love your approach to this. I agree that sharing the responsibility of caring for animals is a wonderful opportunity to build community. If you see an animal in need it is always in good taste to care for it. Animals will befriend people who do this. The friendship that is built is worth every moment and cent that goes toward caring for the animal. Think of feeding the birds and squirrels. We do not own them, yet we are blessed when they come around and communicate with us.
I hope all goes well with the grey cat. He would be lucky to have so many doting caretakers around.
Blessings,
Janet
