Hi. I really don't know what to feed my cat now. They say no dairy and no meat for Sinusitis. I don't even know what to grease his pills with and am doing it with a timy amount of pureed chicken. He vomited it up and is now sounding croupy again. Do you know of anything that will help to get rid of the phlegm in his throat? I've tried the vaporizer again but it's still there. I've heard of Benedryl DM being used but not sure that's correct and I can't get it where I'm located. Anything that can be added to the vaporizer that's an expectorant? Any over-the-counter products that are safe for cats? Thank you,again, for any input you may have.
