Fontline for feral cats

Hi. I wanted to get advice if it is okay to continue to give my feral cats Frontline monthly. I have been doing it.is know they can get reinvested but I feel like it can only help.

Frontline works well as long as you are able to handle the cats and get the liquid onto their fur.  I would definitely use it if you are able to.

I used to squirt the Frontline Plus on my outdoor feral while he was eating his favorite meal, roast chicken, and although it would annoy him, it never annoyed him enough to stop eating. I think it definitely helps. Apply it during dry weather, not when it's raining. Ticks can especially pose a problems for ferals and cause anemia, so you are helping him out. You can purchase Frontline on ebay for about a third of the cost of anywhere else.
