I'm leary of anything made by Seargent's....they make flea treatment/prevention that is really harmful to our furbabies.
I would recommend that you try some all-natural, homemade treats for your furbaby, as well as raw fresh veggies, like frozen peas or small bites of banana or carrots.
I found them online...it's interesting that they don't list the ingredients, just a brief description of the product...makes me raise an eyebrow.
