House Sitting vs Cat Sitting pricing?

I see the list of services that my pet sitter offers. I would the sitter to stay at my place with my cat. There are different prices listed under House sitting. There is a general fee that is across from House sitting and then there are different amounts next to cat sitting, dog sitting, puppy sitting etc. Will the price I pay be the price across from house sitting + the price across from cat sitting. Or will the cat sitting fee be the amount that I would expect to pay? So if it says house sitting = $25 & cat sitting = $15, will I be paying $40/night or $15/night?

Thanks!
