Bella's health has stabilized, but the horizons of her world have foreshortened. She can't patrol as she once did. One indignity is that raccoons have been coming into the yard at night and gathering peanuts I've scattered for squirrels and Bella. The raccoons wash the peanuts for easier eating in Bella's drinking dishes, fouling her water with dirt in the process.
Nevertheless, these raccoons probably don't live in the palm tree located in the corner of the cemetery, near where we rest on our walks. After studying that tree, and listening to the squeaks, I'm now of the opinion that rats inhabit the palm tree fronds. A tree top strikes me as an odd home for rats, but it may provide advantages to small mammals.
