Oh no, not our little Sophie bunster girl... I know how worried you must be Tonya. But on a hopeful note, the majority of large, fast growing growths are benign fatty tumors of cysts. Me and all the furry ones here will be praying with all of our paw power that this dearest, most precious little one will get an encouraging report at the vets. We love you Sophie! And you too, of course Tonya. Love and hugs to our dear friends, Sandra and the Fur Family.
