The pet fee is added to the renting total, it is not a separate line.
What Customer Service says is not true, it was in former days when the pet fee could only be mentioned in description of the listing.
I simulated a booking on your listing for 1 night on 17 april, 1 person, no pet: $275,-
With 1 pet it is: $375,- (same as with 2 pets)

I also simulated an inquiry: same result
