Pet Walker - Full-time / Part-time

My cat is Elvis. He is 13 years old and currently fussy about eating his dry food. He is a love bug and currently working on determining if he has a health concern (has lost weight, drinking lots of water, and has no interest in dry food) which is not diabetes or kidney disease. Tootsie is my 10-month-old miniature schnauzer. I do not want her left alone for more than 5-6 hours and not overnight. She needs 1-2 daily walks and lots of love.
