Hi Debbie! It is great to hear from you!

Debbie, just to be on the safe side, I think I would use Revolution on CJ if he is going to be going outside. The reason I like Revolution for Butter is that it also has the heart worm preventative. Better safe than sorry, I would think.

Hugs to CJ. Why is the little girl's name escaping me right now? Hugs to her, too!
