  Since Sentinel has the flea prevention along with the heartworm prevention, I don't use the advantix II.  Instead, I run my fingers all over their body to check for ticks.  Luckily, we don't really have issues with fleas in my area but I use the flea comb once in a while to double check. 
So far so good with both Magnus/Zoey.  I haven't seen any negative reaction so I'll keep them on this stuff unless I hear/see otherwise.
