A dog or cat scratching the same doorframe or chewing the same chair leg has usually found something they like about it, and telling them not to rarely sticks. Beaphar's Pet Behave works by making the surface itself unpleasant instead.

It uses citronella herb oil at 6.27g/kg, a smell and taste most cats and dogs find unpleasant, sprayed onto the furnishings, woodwork or other items you want left alone rather than onto the animal. Beaphar's own guidance is to repeat the spraying every 2-3 days until the habit stops.

• Citronella herb oil, 6.27g/kg
• Sprayed onto furnishings, not the animal
• For indoor training against chewing and scratching
• Repeat every 2-3 days until the habit stops
• 125ML bottle

One thing worth knowing. This goes on the item you want protected, not on your pet — Beaphar are explicit that it shouldn't be applied directly to an animal, so it works by making the surface unappealing rather than by treating the pet's behaviour directly.

Who it's for: owners with a specific piece of furniture, doorframe or item being chewed or scratched repeatedly, who want a scent-based deterrent rather than a training aid aimed at the animal.
