This calculator helps cat sitters determine their pricing based on various factors like visit duration, frequency, and additional services. It also helps cat owners understand the costs involved.
Standard visit is 30 minutes.
Charge for every 15 minutes beyond the base duration.
Add a percentage for holidays.
Fee for administering medication during a visit.
Fee for each cat beyond the first one.
