I just got a little creative now since I have to stick by the house and wait for a phone call and can't go out to the store. I took a richly scented perfume candle and sat it in a dish on the seat in the car. It is quite warm outside and I think the heat inside the car will cause the candle to give off some of its odor. Of course this is only temporary, but it will probably make the ride to PetsMart tomorrow more pleasant.
