Seeking Part-time Senior Care Provider

About who needs care: My dad is a Diabetic that needs insulin to control his glucose level. He and my Mom both have dementia and have trouble remembering how much and when to take his insulin. My sister (who lives with them and is a teacher) will have pre- loaded shots and instructions as to when he will need to self administer his insulin. He's had 3 strokes and is weak but he can use a walker. My mom is in pretty good health and shouldn't need any assistance with her personal needs. My dad will likely need help with bathing occasionally of which my mom could assist. They may ask for a small grocery or lunch pick up. Note for those with allergies-They do have 3 cats that are inside and outside... My parents are a sweet Christian couple that have been married for 50+ years and need some help caring for my dad. Thank you Services needed include: transportation, meal preparation, errands / shopping, light housekeeping, feeding, and bathing / dressing.
