I think that squirrels were put on Earth by God for our sick entertainment. ;-)
My older Lab actually caught one (it must have been a really slow squirrel). He bit her several times on the nose, but that was his last activity on mortal Earth.
She had to have IV antibiotics and she bled like a pig. But she was very pleased with herself as she trotted out of the shrubbery, covered with her own and the squirrel's blood and grinning from ear to ear around the corpse in her mouth.
...actually God must have put squirrels on Earth for our sick entertainment...AND so that He could be cheaply entertained by OUR invented methods of keeping squirrels from bugging US. LOL.
