When used with citronella, garden torches are not safe for cats if they spend time close by to the feature. Garden torches serve two functions: firstly, to provide ambient lighting in the garden, and secondly, when combined with citronella oil, they can help to ward off flying insects and bugs. Compared to candles, citronella-infused garden torches usually contain higher concentrations of the oil, so you should ensure your cat is kept well clear as much as possible. If they do come into contact with the oil or fumes, it could cause severe health complications.
