Yes, toltrazuril is thick and should be shaken before measuring. Yes, mine, Baycox is also a suspension. Always follow the instructions on the bottle.The bottle I have is a suspension. It's a thick liquid that has to be shaken really well because the medication settles on the bottom of the bottle. The manufacturer of my bottle says to give it orally, not in water.
@Flygirl1987, what product do you have?
