You will drive yourself mad dwelling on what you cannot change. Living in the country I have seen strays and have adopted all that I could. All my life, my pets have been other people’s castoffs and throwaways. I would dissolve into a heap if I thought about all the ones I couldn’t save. I simply concentrate on the ones I was able to rescue.(They are my found tresures.) Keeps me sane, warms my heart and makes me smile. :)
Good advice, we can’t save them all but we can save those that find us.
I do have my adopted pal Squeek but she's "just around"...if you know what I mean. She's company tho since I live alone.
