? Revolution on the area where I give the injections

It is time for the cats to get their flea treatment. Just want to make sure that it is ok to put the Revolution in the same area that I give Shiloh her insulin injections?

 

I would try to avoid shooting in the same location as the preventative, as you wouldn't want to contaminate the syringe needle, nor inadvertently inject a miniscule amount of the topical. Maybe move the shot to the lower shoulders or towards the flanks.
