I the kong can be found at petsmart for sure....and my petsmart just recently started carrying the cowboy magic!
I was very surprised when I was looking around the other day and came across it. The manager of Petsmart here in town uses it on her dogs and she finally worked and got it into stock...I am not sure if the petsmart in your town will carry it as well....as for the Gel I dont know I have never heard of it.
I would try petsmart for the kong and cowboy magic...or any animal supply store that supplies all animals goods!
