We will be moving to Panama (pedasi) this year and will be taking our two cats with us,flying from vancouver BC via Houston.We plan to break our journey in Houston for one night.Does anyone have advice e.g.will US allow us to bring our pets in for one night?We have all the relevant papers for the cats for arrival in Panama but are unsure about the US. Has anyone had experience of this nature? If so can you pass it on to us?
