Animal Care Needed - Full-time / Part-time

My sweet boy is 12yrs old and just diagnosed with cancer. He is very chill, sleeps a good bit and enjoys sunbathing on the deck. I'm looking for a compassionate, caring individual who can keep him company at my home one day a week, 8am-5pm, while I am working. (Usually Wednesdays, but can do Tuesday's or Thursdays if necessary) Must be able to administer medication(pill form) and comfortable changing his diaper. The diaper is only to protect from drainage of mast cell tumor. Fenced in yard, no walks necessary.
