We have an indoor cat, very friendly cat too
We also have a 1 year old and planning to get a nanny as childminder is not really working out for him
My worry is that when the cat poos, it's so smelly and you really don't want to sit in the flat with that smell! But I guess its not really the nanny's job to clean up after the cat poo 
What do people do? Do you ask your nanny to poop scoop and include it as part of their responsibility? Is that a reasonable ask?
