Since you are registered as a business (LLC?), do you not have to claim the income and pay taxes on it?

There will be some months where I'm triple booked (one overnight with 3 "kitty visits" was the most I did for a weekend... was SO busy!), some months where I get a few overnights back to back (longest stretch was 3 1/2 weeks of overnights), and other months where I am dead and wish I had some work. Thankfully I have a few very loyal repeat clients who pay me very generously (seriously, one of them goes out of time multiple times a month sometimes, or will give me a day's notice for an overnight... and if I can I always say yes because the dogs are so easy and she pays so well!) so it makes up for the dead time. I made a large down payment on my new car AND paid for a brand new fancy washer and dryer when we moved into our new house due to money saved up over the past year from pet sitting alone!

Good luck with whatever you decide to do! Sounds like you already have it figured out
