Snowball Has An Allergy

My middle cat Snowball has an allergy and a sinus infection. He is on eye drops, antibiotics, and children's liquid Benadryl. Did you know that children's Benadryl is on backorder at all of our pharmacies, and so I had to get a generic version? I bought the Walgreens' generic, cherry flavored. I called Snowball's doctor to make sure that the cherry flavor would be o.k. for him. It is. I didn't know that cats could take children's Benadryl (or a generic). Snowball's doctor said that cats and dogs cannot take Tylenol (acetaminophen), Ibuprofen, or Pepto-Bismol. Aspirin is deadly to cats. Snowball's eyes are not running much anymore, and he is not sneezing as much now. Thank goodness for good cat doctors.
