I was on the phone with my daughter at the time. She knew why I was hanging up and she immediately emailed me and said she'd find out what the best thing to do would be. She grew up with a cat who used to drop all kinds of little animals in her bedroom that we tried to nurse back to health.
I love all animals and this little creature was so cute. I teach my dog not to attack other animals and he knows what I expect of him, though I've seen him chase moving wildlife when he thinks I'm not watching. But he knew to be gentle when I showed him the vole. That's the wording I use. BE GENTLE. I say that over and over. So he sniffed, but would not have dared open his mouth to hurt the tiny life. And my cat, Sweetie, didn't want to hurt the vole either. In fact, the vole crawled up under her tummy and cuddled beneath her tail for awhile. Pictured above is the vole on her head and my kitty just let the vole sit there!
My daughter called me with great contact information. She found a wildlife rehab person in my area who would have taken the vole if need be and would have treated the wounds. She also found a vet I could email photos of whatever animal was injured and I could get an identification plus medical care for free if needed. I was so impressed. She's incredible at problem solving! She's loved animals since she was a young child.
The advice my daughter had for me was to release the vole back into the bushes in a protected area from the elements so she/he could stay warm. For now, I put some clothes in a cardboard box and put her where she could crawl into a hole in a tree or dig into the ground. I think she might still be in a little shock and need some extra warmth before venturing out on her own. I hope she finds her way back home or to safety somewhere.
*Update: It's been a couple of hours and I checked on the vole. The box is empty, which is what I hoped. I will believe she is going to heal and get on with living.
