Stable income: Somewhat stable

I’d rate it a 3 out of 5 because while pet boarding can provide a decent baseline income, it is not entirely predictable. Demand can fluctuate based on seasons, holidays, and local competition. It's more stable than some side hustles due to the consistent need for pet care, but unexpected cancellations or changes in client needs can create variability. It's not a 2 because there is a regular demand, but not a 4 because it lacks the predictability of a steady paycheck.
