Are you thinking of the
Boundary Sprays from Lambert Kay?? (see link!)
Boundary Indoor/Outdoor Pet Repellant Keep your pets away from furniture, carpet, trees, shrubs, garbage cans/bags, and other “forbidden” areas. Boundary® will repel dogs and cats for up to 24 hours when applied daily. Use in accordance with label directions with consistent training.
I believe the major pet stores carry it (PetCo, Petsmart, etc)... I know the ones in my area do.
