How should i handle a cat not listed?

Jennie, your instincts are correct. If something should happen to the cat, you would be held responsible for it. By telling you to make sure the cat doesn't get out, the owner is in effect directing you to take care of the cat. Unless the cat was kept in a cage (something I am not advocating), the cat needs to be listed and a fee charged. You can determine what is appropriate but IMO your fees are pretty low.

Agree that the cat should be listed. If you will not be responsible for cleaning up after the cat at all, (considering that you will be booking two dogs), you could offer a middle ground solution of charging it at your rates for Additional Cat. To achieve that, you may need to enter a -$ cost adjustment.

I am also struggling with the exact same thing. The day of the lady tells me to feed the cat once a day and clean the litter box. I am missing out on money since the sitting job is 10 days and she did not post the cat but only the dog. I don’t want to come across as to aggressive and need suggestions on how to handle the situation.
