Thanks guys!
I am just trying to figure out what the best product for my baby and I. They all sound good to me. Frontline is close to 14.00 a month, but I didn't know that I could use a little at a time on him. That would save alot. When I run out I am going to ask my vet about these different meds. If any of you have anymore advice I am listening!!!
I have him on heartguard too like I said in my original post.
