I travel mainly on foot and sometimes by bus (I'm a very eco-friendly cat-sitter!) so, as catchment areas go, mine isn't massive. Basically, if you live within 1km of St Catherine's - the church at the top of Telegraph Hill - then you're very probably in my catchment area; plus I cover pretty much all of Nunhead.
The map below shows areas other than Nunhead which I cover. If you live just outside this area, please feel free to get in touch as I may be able to help you, or recommend another trusted cat-sitter if I can't do the visits myself.
