Can you give anithistamines to cats?

Yes, some antihistamines can be given to cats, but it's essential to consult a veterinarian first. Common antihistamines like diphenhydramine (Benadryl) can be used, but the correct dosage and suitability depend on the cat's health and specific condition. Never give your cat any medication without professional guidance, as some human medications can be toxic to pets.
