You could potentially try a dose of an anti-histamine but it is important to differentiate these signs from those of an infection. Viral respiratory infections are extremely common in kitties are the more likely cause of the clinical signs you are describing for Lucy. These infections are typically self-limiting and will resolve without medications. If the nasal discharge changes to green mucus, she will likely need an antibiotic.
