Cats can be very sensitive to flea treatment products, and toxicity can occur from using two products at the same time. Because of that, it's not safe to give the flea drops and then put on the flea collar. Typically the flea drops should be enough to protect Tinkerbell from fleas, and I recommend using only that. I hope this helps!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I do not recommend combining Hartz products. It is a notoriously known company to cause side effects. I would change brands once the collar expires. I recommend the Seresto collar or the oral formulations for ticks (Nexgard, Simparica or Bravecto). Have a good day!

Hello, I would consider using an alternative product. There has been increased number of adverse reactions with the hartz flea product and would not feel comfortable using both concurrently. I would recommend using either the collar or the drops. Alternatively, there are other products in the market you could consider as well such as advantage or frontline. Hope this helps and best of luck
