I have returned from vacation and found my cat (Lucy) has fleas. As I research this invasion, I realize this is pretty insidious. although it may be impossible to figure out the vector for fleas coming in (Lucy is never outside), it may have been my cat sitter, who has a dog - perhaps not, and frankly it's not overly important at this point. Lucy has an appointment with the vet tomorrow and we'll get her treated. I know that I have a lot of laundry to do, and I need to take care of other details in the home as a preventative and longer term management measure. My question is about the availability of NyGuard in Canada. I find recommendations for NyGuard as it is non toxic and effective; however, I cannot find any retail source in Canada. Does anyone know of any Canadian dealer or distributors that carry NyGuard Plus, or NyGuard EZ1?
