    Hi Kim, while not a herbal or natural approach if you’re looking more for that, human antihistamines can be used safely in cats. If your cat has predictable seasonal allergies, you can start one just prior to the start of the season and continue it as needed through the end. Individuals may respond slightly different to different antihistamines, so it can be a trial and error process, but the article I wrote on the topic, <b style=”font-family: inherit; font-size: inherit;”>6 Antihistamines for Cats: Indications for Use, Dosage, and Side Effects is a good starting point.
