When I was a kid, my neighbor that lived onna farm had a stroke. She was hospitalized for weeks and in a nursing home for about 4 months.
In her abscence, I cared for her: horse, 2 ponies, a goat, dozens of chickens and rabbits, 3 dogs (2 inside, 1 outside) and 5 cats (2 inside, 3 outside), and a goldfish tank (55 gallons, and it had 3 fancy goldies in it).
I milked the goat twice a day, gathered eggs each morning, and put all in the fridge for another neighbor who would take it to sell at a farmer's market.
I fed all the animals twice a day, cleaned out the pens they lived in, turned the horse and ponies out into a pasture in the morning and back into the barn in the evening.
I walked the two inside dogs before school, after school, and right before bedtime. I played with the outside dog and cats every day.
I did a 50% water change on the fish aquarium every week.
During the amost 5 months the lady was gone, I did this all myself.
I was 14.
