Instructions
Use a citrus-based spray around the vent (something that won't stain your floors or the vent). Cats generally do not like the smell of citrus and will stay away from anything containing that scent.
Apply double-sided tape or aluminum foil to the area around the vent. Most cats do not like the feeling of sticky tape against their sensitive pads and won't walk on it. Cats also generally do not like the texture of aluminum foil or the sound the foil makes when they step on it.
Place a carpet runner upside down around the vent. The rubber spikes on the underside should keep the kitty away.
Shake a jar of coins whenever the cat goes near the vent. The loud sound will startle her, and eventually she will associate that noise with going near the vent and avoid it. Also try squirting the cat with water when she gets too close to the vent.
Place a motion detector near the floor vent. The cat will associate the noise of the alarm with going near the vent and will probably find some other place to keep warm.
