That's a real good question. At first I was going to say "yes" if it's a paid service, because people with cats on meds go away too, but after you mentioned liability, I got to thinking. Would that mean you'd have to turn down families with cats on meds? Or, perhaps you could have a meeting session with the cat you were to sit to have the owner show you the ins and outs of medicating, and if it didn't look like the cat would be able to work with you, then the owners would have time to find other alternatives.

Or, perhaps you could put a disclaimer in your notice regarding meds?
