Does anybody have the pets at home car harness? We bought it for Alfie when we first had him and are a little concerned. We love the harness itself but the bit that attaches to the seatbelt seems a bit short. We went back in PAH and had a look at the others of the same style and they are all the same. At the moment it's ok as Alfie just sleeps in the car, but I'm a little concerned that on a longer journey he won't be able to move much. I know that is the whole point in them, but it's unlikely he'll be able to sit up when he gets bigger with this. Does anybody else have the PAH harness and have the same issue??
