The Cartier dealer will not sell you a genuine Cartier strap unless you bring in your Genuine Cartier Santos 100 watch to have it fit. The only way to get a genuine Cartier strap without owning a genuine Santos 100 is on the secondary market like a used Watch dealer or on the Bay. The going price for an authentic alligator strap seems pretty steep.
I did come across an italian strap maker which seems to be making very high quality Alligator straps at a price almost equal to the genuine straps on eBay but I am hesitant to pull the trigger. Otherwise, it's Time Republic for 200.
