When Should I Give my Cat ThunderWunders? And How Many?

If possible, give your cat the recommended dose of ThunderWunders ~30 minutes before the stressful event (a thunderstorm is coming, fireworks will start, you are going to get in the car and go to the vet, etc) in order to give the ThunderWunders time to kick in!

ThunderWunders are only meant for cats 12 weeks and older!  The recommended dosage depends on your cat's weight (see chart below).
